The cybersecurity world is filled with jargon and lingo. At TechCrunch, we’ve been writing about cybersecurity for years, and we ceaselessly use technical phrases and expressions to explain the character of what’s occurring on the planet. That’s why we’ve created this glossary, which incorporates a few of the most typical — and never so widespread — phrases and expressions that we use in our articles, and explanations of how, and why, we use them.
It is a creating compendium, and we are going to replace it often. When you have any suggestions or solutions for this glossary, get in contact.
A sophisticated persistent risk (APT) is usually categorized as a hacker, or group of hackers, which good points and maintains unauthorized entry to a focused system. The principle intention of an APT intruder is to stay undetected for lengthy intervals of time, usually to conduct espionage and surveillance, to steal information, or sabotage essential techniques.
APTs are historically well-resourced hackers, together with the funding to pay for his or her malicious campaigns, and entry to hacking instruments sometimes reserved by governments. As such, most of the long-running APT teams are related to nation states, like China, Iran, North Korea, and Russia. In recent times, we’ve seen examples of non-nation state cybercriminal teams which are financially motivated (equivalent to theft and cash laundering) finishing up cyberattacks related when it comes to persistence and capabilities as some conventional government-backed APT teams.

The flexibility to run instructions or malicious code on an affected system, usually due to a safety vulnerability within the system’s software program. Arbitrary code execution will be achieved both remotely or with bodily entry to an affected system (equivalent to somebody’s gadget). Within the instances the place arbitrary code execution will be achieved over the web, safety researchers sometimes name this distant code execution.
Usually, code execution is used as a option to plant a again door for sustaining long-term and protracted entry to that system, or for working malware that can be utilized to entry deeper components of the system or different units on the identical community.
(See additionally: Distant code execution)
Attribution is the method of discovering out and figuring out who’s behind a cyberattack. There may be an usually repeated mantra, “attribution is difficult,” which is to warn cybersecurity professionals and the broader public that definitively establishing who was behind a cyberattack isn’t any easy process. Whereas it’s not unimaginable to attribute, the reply can be depending on the extent of confidence within the evaluation.
Risk intelligence firms equivalent to CrowdStrike, Kaspersky, and Mandiant, amongst others, have for years attributed cyberattacks and information breaches to teams or “clusters” of hackers, usually referencing teams by a selected codename, primarily based on a sample of sure techniques, strategies and procedures as seen in earlier assaults. Some risk intelligence corporations go so far as publicly linking sure teams of hackers to particular governments or their intelligence companies when the proof factors to it.
Authorities companies, nevertheless, have for years publicly accused different governments and nations of being behind cyberattacks, and have gone so far as figuring out — and generally criminally charging — particular individuals working for these companies.
A backdoor is a subjective time period, however broadly refers to creating the means to realize future entry to a system, gadget, or bodily space. Backdoors will be present in software program or {hardware}, equivalent to a mechanism to realize entry to a system (or house) in case of unintended lock-out, or for remotely offering technical assist over the web. Backdoors can have reputable and useful use instances, however backdoors may also be undocumented, maliciously planted, or in any other case unknown to the person or proprietor, which might weaken the safety of the product and make it extra inclined to hacking or compromise.
Hackers traditionally have been categorized as both “black hat” or “white hat,” normally relying on the motivations of the hacking exercise carried out. A “black hat” hacker could also be somebody who would possibly break the regulation and hack for cash or private achieve, equivalent to a cybercriminal. “White hat” hackers usually hack inside authorized bounds, like as a part of a penetration take a look at sanctioned by the goal firm, or to gather bug bounties discovering flaws in varied software program and disclosing them to the affected vendor. For many who hack with much less clearcut motivations, they might be considered a “grey hat.” Famously, the hacking group the L0pht used the time period grey hat in an interview with The New York Occasions Journal in 1999. Whereas nonetheless generally utilized in fashionable safety parlance, many have moved away from the “hat” terminology.

Botnets are networks of hijacked internet-connected units, equivalent to webcams and residential routers, which were compromised by malware (or generally weak or default passwords) for the needs of being utilized in cyberattacks. Botnets will be made up of lots of or hundreds of units and are sometimes managed by a command-and-control server that sends out instructions to ensnared units. Botnets can be utilized for a variety of malicious causes, like utilizing the distributed community of units to masks and defend the web visitors of cybercriminals, ship malware, or harness their collective bandwidth to maliciously crash web sites and on-line companies with big quantities of junk web visitors.
(See additionally: Command-and-control server; Distributed denial-of-service)
A bug is basically the reason for a software program glitch, equivalent to an error or an issue that causes the software program to crash or behave in an surprising manner. In some instances, a bug may also be a safety vulnerability.
The time period “bug” originated in 1947, at a time when early computer systems have been the dimensions of rooms and made up of heavy mechanical and transferring tools. The primary identified incident of a bug present in a pc was when a moth disrupted the electronics of certainly one of these room-sized computer systems.
(See additionally: Vulnerability)
Command-and-control servers (also referred to as C2 servers) are utilized by cybercriminals to remotely handle and management their fleets of compromised units and launch cyberattacks, equivalent to delivering malware over the web and launching distributed denial-of-service assaults.
(See additionally: Botnet; Distributed denial-of-service)
Cryptojacking is when a tool’s computational energy is used, with or with out the proprietor’s permission, to generate cryptocurrency. Builders generally bundle code in apps and on web sites, which then makes use of the gadget’s processors to finish advanced mathematical calculations wanted to create new cryptocurrency. The generated cryptocurrency is then deposited in digital wallets owned by the developer.
Some malicious hackers use malware to intentionally compromise giant numbers of unwitting computer systems to generate cryptocurrency on a big and distributed scale.
Once we speak about information breaches, we in the end imply the improper removing of knowledge from the place it ought to have been. However the circumstances matter and may alter the terminology we use to explain a selected incident.
An information breach is when protected information was confirmed to have improperly left a system from the place it was initially saved and normally confirmed when somebody discovers the compromised information. As a rule, we’re referring to the exfiltration of knowledge by a malicious cyberattacker or in any other case detected on account of an inadvertent publicity. Relying on what is thought concerning the incident, we could describe it in additional particular phrases the place particulars are identified.
(See additionally: Information publicity; Information leak)
An information publicity (a kind of knowledge breach) is when protected information is saved on a system that has no entry controls, equivalent to due to human error or a misconfiguration. This would possibly embrace instances the place a system or database is related to the web however with no password. Simply because information was uncovered doesn’t imply the information was actively found, however nonetheless might nonetheless be thought-about a knowledge breach.
An information leak (a kind of knowledge breach) is the place protected information is saved on a system in a manner that it was allowed to flee, equivalent to resulting from a beforehand unknown vulnerability within the system or by means of insider entry (equivalent to an worker). An information leak can imply that information might have been exfiltrated or in any other case collected, however there could not at all times be the technical means, equivalent to logs, to know for positive.
Def Con is without doubt one of the most vital hacking conferences on the planet, held yearly in Las Vegas, normally throughout August. Launched in 1993 as a celebration for some hacker pals, it has now change into an annual gathering of just about 30,000 hackers and cybersecurity professionals, with dozens of talks, capture-the-flag hacking competitions, and themed “villages,” the place attendees can discover ways to hack internet-connected units, voting techniques, and even plane. Not like different conferences like RSA or Black Hat, Def Con is decidedly not a enterprise convention, and the main target is way more on hacker tradition. There’s a vendor space, however it normally consists of nonprofits just like the Digital Frontier Basis, The Calyx Institute, and the Tor Challenge, in addition to comparatively small cybersecurity firms.
A distributed denial-of-service, or DDoS, is a form of cyberattack that includes flooding targets on the web with junk internet visitors with a purpose to overload and crash the servers and trigger the service, equivalent to an internet site, on-line retailer, or gaming platform to go down.
DDoS assaults are launched by botnets, that are made up of networks of hacked internet-connected units (equivalent to dwelling routers and webcams) that may be remotely managed by a malicious operator, normally from a command-and-control server. Botnets will be made up of lots of or hundreds of hijacked units.
Whereas a DDoS is a type of cyberattack, these data-flooding assaults are usually not “hacks” in themselves, as they don’t contain the breach and exfiltration of knowledge from their targets, however as an alternative trigger a “denial of service” occasion to the affected service.
(See additionally: Botnet; Command-and-control server)
Encryption is the way in which and means during which data, equivalent to recordsdata, paperwork, and personal messages, are scrambled to make the information unreadable to anybody apart from to its supposed proprietor or recipient. Encrypted information is usually scrambled utilizing an encryption algorithm — basically a set of mathematical formulation that determines how the information must be encrypted — together with a non-public key, equivalent to a password, which can be utilized to unscramble (or “decrypt”) the protected information.
Almost all fashionable encryption algorithms in use at this time are open supply, permitting anybody (together with safety professionals and cryptographers) to assessment and test the algorithm to ensure it’s freed from faults or flaws. Some encryption algorithms are stronger than others, that means information protected by some weaker algorithms will be decrypted by harnessing giant quantities of computational energy.
Encryption is totally different from encoding, which merely converts information into a distinct and standardized format, normally for the good thing about permitting computer systems to learn the information.
(See additionally: Finish-to-end encryption)
Finish-to-end encryption (or E2EE) is a safety function constructed into many messaging and file-sharing apps, and is broadly thought-about one of many strongest methods of securing digital communications as they traverse the web.
E2EE scrambles the file or message on the sender’s gadget earlier than it’s despatched in a manner that permits solely the supposed recipient to decrypt its contents, making it near-impossible for anybody — together with a malicious hacker, and even the app maker — to snoop inside on somebody’s personal communications. In recent times, E2EE has change into the default safety normal for a lot of messaging apps, together with Apple’s iMessage, Fb Messenger, Sign, and WhatsApp.
E2EE has additionally change into the topic of governmental frustration in recent times, as encryption makes it unimaginable for tech firms or app suppliers to provide over data that they themselves would not have entry to.
(See additionally: Encryption)
Most fashionable techniques are protected with a number of layers of safety, together with the flexibility to set person accounts with extra restricted entry to the underlying system’s configurations and settings. This prevents these customers — or anybody with improper entry to certainly one of these person accounts — from tampering with the core underlying system. Nonetheless, an “escalation of privileges” occasion can contain exploiting a bug or tricking the system into granting the person extra entry rights than they need to have.
Malware can even benefit from bugs or flaws attributable to escalation of privileges by gaining deeper entry to a tool or a related community, probably permitting the malware to unfold.
Once we speak about espionage, we’re usually referring to risk teams or hacking campaigns which are devoted to spying, and are sometimes characterised by their stealth. Espionage-related hacks are normally geared toward gaining and sustaining stealthy persistent entry to a goal’s community to hold out passive surveillance, reconnaissance for future cyberattacks, or the long-term assortment and exfiltration of knowledge. Espionage operations are sometimes carried out by governments and intelligence companies, although not solely.
An exploit is the way in which and means during which a vulnerability is abused or taken benefit of, normally with a purpose to break right into a system.
(See additionally: Bug; Vulnerability)
Typically phrases, extortion is the act of acquiring one thing, normally cash, by using power and intimidation. Cyber extortion isn’t any totally different, because it sometimes refers to a class of cybercrime whereby attackers demand fee from victims by threatening to break, disrupt, or expose their delicate data.
Extortion is usually utilized in ransomware assaults, the place hackers sometimes exfiltrate firm information earlier than demanding a ransom fee from the hacked sufferer. However extortion has shortly change into its personal class of cybercrime, with many, usually youthful, financially motivated hackers, opting to hold out extortion-only assaults, which snub using encryption in favor of straightforward information theft.
(Additionally see: Ransomware)
Forensic investigations contain analyzing information and knowledge contained in a pc, server, or cell gadget, on the lookout for proof of a hack, crime, or some form of malfeasance. Generally, with a purpose to entry the information, company or regulation enforcement investigators depend on specialised units and instruments, like these made by Cellebrite and Grayshift, that are designed to unlock and break the safety of computer systems and cellphones to entry the information inside.
There isn’t a one single definition of “hacker.” The time period has its personal wealthy historical past, tradition, and that means throughout the safety group. Some incorrectly conflate hackers, or hacking, with wrongdoing.
By our definition and use, we broadly consult with a “hacker” as somebody who’s a “breaker of issues,” normally by altering how one thing works to make it carry out in another way with a purpose to meet their targets. In apply, that may be one thing so simple as repairing a machine with non-official components to make it operate in another way as supposed, or work even higher.
Within the cybersecurity sense, a hacker is usually somebody who breaks a system or breaks the safety of a system. That might be something from an internet-connected laptop system to a easy door lock. However the particular person’s intentions and motivations (if identified) matter in our reporting, and guides how we precisely describe the particular person, or their exercise.
There are moral and authorized variations between a hacker who works as a safety researcher, who’s professionally tasked with breaking into an organization’s techniques with their permission to establish safety weaknesses that may be fastened earlier than a malicious particular person has an opportunity to take advantage of them; and a malicious hacker who good points unauthorized entry to a system and steals information with out acquiring anybody’s permission.
As a result of the time period “hacker” is inherently impartial, we usually apply descriptors in our reporting to offer context about who we’re speaking about. If we all know that a person works for a authorities and is contracted to maliciously steal information from a rival authorities, we’re prone to describe them as a nation-state or authorities hacker (or, if acceptable, an superior persistent risk), for instance. If a gang is thought to make use of malware to steal funds from people’ financial institution accounts, we could describe them as financially motivated hackers, or if there’s proof of criminality or illegality (equivalent to an indictment), we could describe them merely as cybercriminals.
And, if we don’t know motivations or intentions, or an individual describes themselves as such, we could merely consult with a topic neutrally as a “hacker,” the place acceptable.

Generally, hacking and stealing information is barely step one. In some instances, hackers then leak the stolen information to journalists, or immediately publish the information on-line for anybody to see. The aim will be both to embarrass the hacking sufferer, or to show alleged malfeasance.
The origins of contemporary hack-and-leak operations date again to the early- and mid-2000s, when teams like el8, pHC (“Phrack Excessive Council”) and zf0 have been concentrating on individuals within the cybersecurity business who, in keeping with these teams, had foregone the hacker ethos and had bought out. Later, there are the examples of hackers related to Nameless and leaking information from U.S. authorities contractor HBGary, and North Korean hackers leaking emails stolen from Sony as retribution for the Hollywood comedy, The Interview.
A few of the most up-to-date and well-known examples are the hack towards the now-defunct authorities spy ware pioneer Hacking Crew in 2015, and the notorious Russian government-led hack-and-leak of Democratic Nationwide Committee emails forward of the 2016 U.S. presidential elections. Iranian authorities hackers tried to emulate the 2016 playbook through the 2024 elections.
A selected form of hacker who hacks for what they — and maybe the general public — understand as a superb trigger, therefore the portmanteau of the phrases “hacker” and “activist.” Hacktivism has been round for greater than twenty years, beginning maybe with teams just like the Cult of the Lifeless Cow within the late Nineties. Since then, there have been a number of excessive profile examples of hacktivist hackers and teams, equivalent to Nameless, LulzSec, and Phineas Fisher.

Quick for “data safety,” another time period used to explain defensive cybersecurity centered on the safety of knowledge and knowledge. “Infosec” could also be the popular time period for business veterans, whereas the time period “cybersecurity” has change into broadly accepted. In fashionable occasions, the 2 phrases have change into largely interchangeable.
Infostealers are malware able to stealing data from an individual’s laptop or gadget. Infostealers are sometimes bundled in pirated software program, like Redline, which when put in will primarily hunt down passwords and different credentials saved within the particular person’s browser or password supervisor, then surreptitiously add the sufferer’s passwords to the attacker’s techniques. This lets the attacker sign up utilizing these stolen passwords. Some infostealers are additionally able to stealing session tokens from a person’s browser, which permit the attacker to sign up to an individual’s on-line account as in the event that they have been that person however with no need their password or multifactor authentication code.
(See additionally: Malware)
Jailbreaking is utilized in a number of contexts to imply using exploits and different hacking strategies to avoid the safety of a tool, or eradicating the restrictions a producer places on {hardware} or software program. Within the context of iPhones, for instance, a jailbreak is a method to take away Apple’s restrictions on putting in apps exterior of its “walled backyard” or to realize the flexibility to conduct safety analysis on Apple units, which is generally extremely restricted. Within the context of AI, jailbreaking means determining a option to get a chatbot to give out data that it’s not alleged to.
The kernel, as its identify suggests, is the core a part of an working system that connects and controls nearly all {hardware} and software program. As such, the kernel has the very best stage of privileges, that means it has entry to nearly any information on the gadget. That’s why, for instance, apps equivalent to antivirus and anti-cheat software program run on the kernel stage, as they require broad entry to the gadget. Having kernel entry permits these apps to watch for malicious code.
Malware is a broad umbrella time period that describes malicious software program. Malware can land in lots of types and be used to take advantage of techniques in several methods. As such, malware that’s used for particular functions can usually be known as its personal subcategory. For instance, the kind of malware used for conducting surveillance on individuals’s units can be known as “spy ware,” whereas malware that encrypts recordsdata and calls for cash from its victims is known as “ransomware.”
(See additionally: Infostealers; Ransomware; Spyware and adware)
Metadata is data about one thing digital, fairly than its contents. That may embrace particulars concerning the measurement of a file or doc, who created it, and when, or within the case of digital photographs, the place the picture was taken and details about the gadget that took the photograph. Metadata could not establish the contents of a file, however it may be helpful in figuring out the place a doc got here from or who authored it. Metadata can even consult with details about an trade, equivalent to who made a name or despatched a textual content message, however not the contents of the decision or the message.
Phishing is a kind of cyberattack the place hackers trick their targets into clicking or tapping on a malicious hyperlink, or opening a malicious attachment. The time period derives from “fishing,” as a result of hackers usually use “lures” to convincingly trick their targets in most of these assaults. A phishing lure might be attachment coming from an e mail tackle that seems to be reputable, and even an e mail spoofing the e-mail tackle of an individual that the goal actually is aware of. Generally, the lure might be one thing which may look like vital to the goal, like sending a cast doc to a journalist that seems to indicate corruption, or a pretend convention invite for human rights defenders. There may be an usually cited adage by the well-known cybersecurity influencer The Grugq, which encapsulates the worth of phishing: “Give a person an 0day and he’ll have entry for a day, educate a person to phish and he’ll have entry for all times.”

Ransomware is a kind of malicious software program (or malware) that stops gadget house owners from accessing its information, sometimes by encrypting the particular person’s recordsdata. Ransomware is normally deployed by cybercriminal gangs who demand a ransom fee — normally cryptocurrency — in return for offering the personal key to decrypt the particular person’s information.
In some instances, ransomware gangs will steal the sufferer’s information earlier than encrypting it, permitting the criminals to extort the sufferer additional by threatening to publish the recordsdata on-line. Paying a ransomware gang isn’t any assure that the sufferer will get their stolen information again, or that the gang will delete the stolen information.
One of many first-ever ransomware assaults was documented in 1989, during which malware was distributed by way of floppy disk (an early type of detachable storage) to attendees of the World Well being Group’s AIDS convention. Since then, ransomware has advanced into a multibillion-dollar legal business as attackers refine their techniques and hone in on big-name company victims.
(See additionally: Malware; Sanctions)
Distant code execution refers back to the skill to run instructions or malicious code (equivalent to malware) on a system from over a community, usually the web, with out requiring any human interplay from the goal. Distant code execution assaults can vary in complexity however will be extremely damaging when vulnerabilities are exploited.
(See additionally: Arbitrary code execution)
Cybersecurity-related sanctions work equally to conventional sanctions in that they make it unlawful for companies or people to transact with a sanctioned entity. Within the case of cyber sanctions, these entities are suspected of finishing up malicious cyber-enabled actions, equivalent to ransomware assaults or the laundering of ransom funds made to hackers.
The U.S. Treasury’s Workplace of International Belongings Management (OFAC) administers sanctions. The Treasury’s Cyber-Associated Sanctions Program was established in 2015 as a part of the Obama administration’s response to cyberattacks concentrating on U.S. authorities companies and personal sector U.S. entities.
Whereas a comparatively new addition to the U.S. authorities’s bureaucratic armory towards ransomware teams, sanctions are more and more used to hamper and deter malicious state actors from conducting cyberattacks. Sanctions are sometimes used towards hackers who’re out of attain of U.S. indictments or arrest warrants, equivalent to ransomware crews primarily based in Russia.
Social engineering is the artwork of human deception, and encompasses a number of strategies a hacker can use to deceive their goal into doing one thing they usually wouldn’t do. Phishing, for instance, will be categorised as a kind of social engineering assault as a result of hackers trick targets into clicking on a malicious hyperlink or opening a malicious attachment, or calling somebody on the telephone whereas pretending to be their employer’s IT division.
Social engineering may also be utilized in the true world, for instance, to persuade constructing safety workers to let somebody who shouldn’t be allowed to enter the constructing. Some name it “human hacking” as a result of social engineering assaults don’t essentially need to contain expertise.
(Additionally see: Phishing)
A broad time period, like malware, that covers a variety of surveillance monitoring software program. Spyware and adware is usually used to consult with malware made by personal firms, equivalent to NSO Group’s Pegasus, Intellexa’s Predator, and Hacking Crew’s Distant Management System, amongst others, which the businesses promote to authorities companies. In additional generic phrases, most of these malware are like distant entry instruments, which permits their operators — normally authorities brokers — to spy and monitor their targets, giving them the flexibility to entry a tool’s digital camera and microphone or exfiltrate information. Spyware and adware can be known as business or authorities spy ware, or mercenary spy ware.
(See additionally: Stalkerware)
Stalkerware is a form of surveillance malware (and a type of spy ware) that’s normally bought to unusual customers below the guise of kid or worker monitoring software program however is usually used for the needs of spying on the telephones of unwitting people, oftentimes spouses and home companions. The spy ware grants entry to the goal’s messages, location, and extra. Stalkerware sometimes requires bodily entry to a goal’s gadget, which provides the attacker the flexibility to put in it immediately on the goal’s gadget, actually because the attacker is aware of the goal’s passcode.

What are you attempting to guard? Who’re you apprehensive about that would go after you or your information? How might these attackers get to the information? The solutions to those sorts of questions are what is going to lead you to create a risk mannequin. In different phrases, risk modeling is a course of that a corporation or a person has to undergo to design software program that’s safe, and devise strategies to safe it. A risk mannequin will be centered and particular relying on the state of affairs. A human rights activist in an authoritarian nation has a distinct set of adversaries, and information, to guard than a big company in a democratic nation that’s apprehensive about ransomware, for instance.
Once we describe “unauthorized” entry, we’re referring to the accessing of a pc system by breaking any of its security measures, equivalent to a login immediate or a password, which might be thought-about unlawful below the U.S. Laptop Fraud and Abuse Act, or the CFAA. The Supreme Courtroom in 2021 clarified the CFAA, discovering that accessing a system missing any technique of authorization — for instance, a database with no password — will not be unlawful, as you can not break a safety function that isn’t there.
It’s value noting that “unauthorized” is a broadly used time period and infrequently utilized by firms subjectively, and as such has been used to explain malicious hackers who steal somebody’s password to interrupt in by to incidents of insider entry or abuse by workers.
A digital personal community, or VPN, is a networking expertise that permits somebody to “nearly” entry a non-public community, equivalent to their office or dwelling, from wherever else on the planet. Many use a VPN supplier to browse the online, pondering that this may help to keep away from on-line surveillance.
TechCrunch has a skeptics’ information to VPNs that may make it easier to determine if a VPN is smart for you. If it does, we’ll present you the best way to arrange your individual personal and encrypted VPN server that solely you management. And if it doesn’t, we discover a few of the privateness instruments and different measures you may take to meaningfully enhance your privateness on-line.
A vulnerability (additionally known as a safety flaw) is a kind of bug that causes software program to crash or behave in an surprising manner that impacts the safety of the system or its information. Generally, two or extra vulnerabilities can be utilized along side one another — generally known as “vulnerability chaining” — to realize deeper entry to a focused system.
(See additionally: Bug; Exploit)
Malicious assaults can generally be categorized and described by the quantity of person interplay that malware, or a malicious hacker, wants with a purpose to obtain profitable compromise. One-click assaults consult with the goal having to work together solely as soon as with the incoming lure, equivalent to clicking on a malicious hyperlink or opening an attachment, to grant the intruder entry. However zero-click assaults differ in that they will obtain compromise with out the goal having to click on or faucet something. Zero-clicks are near-invisible to the goal and are far tougher to establish. As such, zero-click assaults are nearly at all times delivered over the web, and are sometimes reserved for high-value targets for his or her stealthy capabilities, equivalent to deploying spy ware.
(Additionally see: Spyware and adware)
A zero-day is a selected kind of safety vulnerability that has been publicly disclosed or exploited however the vendor who makes the affected {hardware} or software program has not been given time (or “zero days”) to repair the issue. As such, there could also be no quick repair or mitigation to stop an affected system from being compromised. This may be significantly problematic for internet-connected units.
