The process of granting or denying specific requests for or attempts to: 1) obtain and use information and related information processing services; and 2) enter specific physical facilities.

Advanced Persistent Threat / APT
Advanced persistent threat is a user or a program that has highly sophisticated techniques and intends to pursue them with a malicious intent. It is deployed by cyber-criminals who have a high level of expertise and important resources to infiltrate a network. They usually use this type of attack to target large organizations seeking to retrieve economic or financial information. In some cases, they might even try to use this form of attack to stop or block a company's program or agenda.
One who opposes or prevents the incoming threats.
Adware is a type of software that delivers ads on your system. Adware is software distributed to the user free of cost with advertisements embedded into them. As such, it displays advertisements, and redirects your queries to sponsor’s websites. Adware helps advertisers collect data for marketing purposes, without your permissions to do so. A user can disable ad pop-ups by purchasing a registration key.
After-Action Report (AAR)
It is a detailed report with an analysis of past happened events with findings and necessary recommendations for the action plans.
AI and ML in Cybersecurity
Creating the required Mathematical algorithms to bring in intelligence into the Cybersecurity process.
All Source Intelligence
It is used to describe intelligence products, organizations, and activities which rely on all available sources of intelligence collection information.
PT Anti-APT detects and prevents targeted attacks. It enables detecting attacker presence on the network with maximum speed and recreating a full picture for thorough investigation. Detects attackers both on the perimeter and inside infrastructure.
Anonymizing proxy
An anonymizing proxy is a way to hide your online activity and/or make it really difficult to be disclosed by third parties, like countries that apply Internet censorship. These proxy servers act like an intermediary connection between your computer and the final target. From an outsider's point of view, they access those web locations and hide your computer's IP from further identification. Usually, they are used to access freely Internet content under strict censorship.
The general usage of this term - Anti-malware - refers to a number of software programs and applications that are capable to detect and remove malware from individual systems or from larger networks. Though the term is usually used in connection with classic antivirus products, the anti-malware abilities can include anti-spyware, anti-phishing or anti-spam solutions. Lately, the term has spread to name specialized software that fights data stealing malware delivered by online criminals.
Anti-spam term or better said the anti-spam techniques are employed by special software programs that fight spam, which is unsolicited e-mail. The spam problem needs to be solved not only at the individual level of each user, but at an even greater level, that of system administrators that need to secure thousands of computers from spam. Spamming attempts become a greater problem for everybody because this is one of the main ways to deliver the most dangerous malware in the wild and additional phishing threats.
Anti-spoofing techniques are used in order to stop the DDoS (Distributed Denial-of-Service) attacks that affect so many websites. To deliver these attacks, hackers are "spoofing" IP addresses, from where they send a great number of requests. When the website server attempts to reply to the requests, it gets stalled by waiting to access servers that actually do not exist. In this case again, it is difficult to detect the source of the attacks, therefore the only available solution is to use a software that can detect these fake IP addresses and refuse the connection.
Antispyware software
A program that specializes in detecting and blocking or removing forms of spyware.
Antivirus software
anti-virus (anti-malware) — A security program designed to monitor a system for malicious software. Once malware is detected, the AV program will attempt to remove the offending item from the system or may simply quarantine the file for further analysis by an administrator. It is important to keep AV software detection databases current in order to have the best chance of detecting known forms of malware.

AutoPlay, a similar technology has been used recently to deliver the infamous Conficker worm. Microsoft has set on new systems the AutoRun setting to off, so this issue should disappear in the future.
Backdoor Trojan

A backdoor Trojan is a way to take control of a system without permission. Usually, a backdoor Trojan poses as a legitimate program spreading though phishing campaigns and fooling users into clicking a malicious link or accessing malware on a website. Once the system is infected, the Trojan can access sensitive files, send, and receive data online and track the browsing history. To avoid this type of infection, you should keep the system up to date with the latest patches and have strong anti-malware protection.

Boot sector malware
A boot sector malware can replicate the original boot sector of the system, so that at the following system boot-up, the malware may become active. This way, the boot kit in the boot sector manages to hide its presence before the operating system can load up. This is a clear advantage for the malware, which is loaded before the system and the anti-malware solution. Since it loads before the security solution, it can even disable it and make it useless against it.This type of infection is usually difficult to clean.
Internet bots or web bots are software programs that perform automated tasks and specific operations.

Domain shadowing is a malicious tactic used by cyber criminals to build their infrastructure and launch attacks while remaining undetected. First, attackers steal and gather credentials for domain accounts. Using these stolen credentials, they log into the domain account and create subdomains which redirect traffic towards malicious servers, without the domain owner having any knowledge of this. Domain shadowing allows cyber attackers to bypass reputation-based filters and pass their malicious traffic as safe.
Dormant code
Modern, advanced malware often has modular structure, including multiple components. One of them is dormant code, which means that the malware needs specific triggers to execute the task is was created for. This type of behavior is coded into the malware to it can bypass signature-based detection in products such as traditional antivirus and anti-malware solutions. There is also another reason for using dormant code: since advanced malware, such as ransomware or financial malware, usually rely on extern frastructure to download components for infection, the malware can remain dormant and undetected if it can’t reach its Control and Command servers to execute further.

Reverse proxies take public HTTP requests and pass them to back-end webservers to send the content to it, so the proxy can then send the content to the end-user.
Risk mitigation
This is the process by which risks are evaluated, prioritized and managed through mitigation tactics and measures. Since any company has a dynamic environment, a periodical revision should be a defining characteristic of the risk mitigation process.
Rogue security software
Rogue security software (usually antivirus) is a common Internet scam used by cyber criminals to mislead victims and infect their PCs with malware. Malicious actors could also use fake antivirus to trick victims into paying money or extort them (like ransomware does) into paying for having the rogue software removed. So please only buy security software from trusted vendors or from the software makers themselves.
This is a type of deceitful malware which claims to be a trusted and harmless software program (such as antivirus). Cyber criminals use rogueware to harvest data from their victims or to trick them intro paying money. Often, rogueware also includes adware functions, which adds a burden and a potential risk to the infected PC.
Role Based Access Control
Role based access control assigns users to roles based on their organizational functions and determines authorization based on those roles.

SIEM Implementation
A SIEM (Security Information & Event Management) is a platform for managing security incidents. It allows the collection of system logs and machine data from across your IT environment to help identify unusual or suspicious activity — and then reports an alert in real time if it finds anything suspicious.
Sensitive Information
This type of information is defined by the fact that not everyone can access it. Sensitive information is data that is confidential for a certain category of users, who can view, access and use this data. This type of information is protected for reasons either related to legal aspects or ethical ones. Examples include: personal identification numbers, health information, education records, trade secrets, credit card information, etc.
In cyber security, a signature is an identifiable, differentiating pattern associated with a type of malware, an attack or a set of keystrokes which were used to gain unauthorized access to a system. For example, traditional antivirus solutions can spot, block and remove malware based on their signature, when the antivirussees that a piece of software on your PC matched the signature of a malicious software stored in their database.
Skimming happens when a malicious actor uses a tag reader in an unauthorized manner, in order to collect information about a person’s tag. The victim never knows or accepts to be skimmed. For example, card skimming is an illegal practice which consists of the illegal collection of data from a card’s magnetic stripe. This information can then be copied onto a blank card’s magnetic stripe and used by malicious actors to make purchases and withdraw cash in the name of the victim.
The Smurf attack works by spoofing the target address and sending a ping to the broadcast address for a remote network, which results in a large amount of ping replies being sent to the target.

Spam is often used to spread malware and phishing, which is why you should never open, reply to or download attachments from spam messages. Spam cam come your way in the form of emails, instant messages, comments, etc.
Spam filtering software
This is a type of program which can analyse emails and other types of messages (i.e. instant messages) to weed out spam. If spam filtering software decides to categorize a message as spam, it’ll probably move that message to a dedicated folder.
Spear phishing
Spear phishing is a cyber-attack that aims to extract sensitive data from a victim using a very specific and personalized message. This message is usually sent to individuals or companies, and it’s extremely effective, because it’s very well planned. Attackers invest time and resources into gathering information about the victim (interests, activities, personal history, etc.) in order to create the spear phishing message (which is usually an email). Spear phishing uses the sense of urgency and familiarity (appears to come from someone you know) to manipulate the victim, so the target doesn’t have time to double check the information.

Information spillage happen when data is moved from a safe, protected system to another system, which is less secure. This can happen to all types of data, from health information to financial or personal data. If the system the data is moved to is less secure, people who should not have access to this information may be able to access it.
Spoofing (Email)
This is a compromise attempt during which an unauthorized individual tries to gain access to an information system by impersonating an authorized user. For example, email spoofing is when cyber attackers send phishing emails using a forged sender address. You might believe that you’re receiving an email from a trusted entity, which causes you to click on the links in the email, but the link may end up infecting your PC with malware.
This is a type of malware that employs tactics found in both phishing and spyware. By combining these cyber threats, spy-phishing is capable of downloading applications that can run silently on the victim’s system. When the victims open a specific URL, the malware will collect the data the victim puts into that website and send it to a malicious location (like a web server). This technique is used to extend the duration of the phishing attack, even after the phishing website has been taken down.
Software that is secretly or surreptitiously installed into an information system without the knowledge of the system user or owner. Spyware monitors and stores the victim’s Internet activity (keystrokes, browser history, etc.) and can also harvest usernames, passwords, financial information and more. It can also send this confidential data to servers operated by cyber criminals, so it can be used in consequent cyber-attacks.
SQL injection
This is a tactic that used code injection to attack applications which are data-driven. The maliciously injected SQL code can perform several actions, including dumping all the data in a database in a location controlled by the attacker. Through this attack, malicious hackers can spoof identities, modify data or tamper with it, disclose confidential data, delete and destroy the data or make it unavailable. They can also take control of the database completely.
SSL / Secure Sockets Layer
SSL comes from Secure Sockets Layer, which is an encryption method to ensure the safety of the data sent and received from a user to a specific website and back. Encrypting this data transfer ensures that no one can snoop on the transmission and gain access to confidential information, such as card details in the case of online shopping. Legitimate websites use SSL (start with https) and users should avoid inputting their data in websites that don’t use SSL.
This is a type of malware which is capable of transferring data or money to a third, malicious party. This type of malware usually targets affiliate transactions. It then uses an HTTP cookie to redirect the commission earned by an affiliate marketer to an unauthorized third party.
Strong authentication
This is a specific requirement that calls for employing multiple authentication factors from different categories and sophisticated technology to verify an entity’s identity. Dynamic passwords, digital certificates, protocols and other authentication elements are part of strong authentication standards. This is especially applied in banking and financial services, where access to an account has to be tied to a real person or an organization.
Supply chain attack
This type of attack aims to inflict damage upon an organization by leveraging vulnerabilities in its supply network. Cyber criminals often manipulate with hardware or software during the manufacturing stage to implant rootkits or tie in hardware-based spying elements. Attackers can later use these implants to attack the organization they’re after.
Suppression measure
This can be any action or device used to reduce the security risks in an information system. This is part of the risk mitigation process, aimed at minimizing the security risks of an organization or information system.
Suspicious files and behavior
Suspicious behavior is identified when files exhibit an unusual behavior pattern. For example, if files start copying themselves to a system folder, this might be a sign that those file have been compromised by malware. Traditional antivirus solutions incorporate this type of detection to spot and block malware.

This state defines an information system which is able to perform its dedicated functions at optimal parameters, without intrusion or manipulation (either intended or not).

The intentional activity of modifying the way an information system works, in order to force it to execute unauthorized actions.

Targeted threat
Targeted threats are singled out because of their focus: they are usually directed at a specific organization or industry. These threats are also designed to extract sensitive information from the target, so cyber criminals take a long time to prepare these threats. They are carefully documented, so the chances for successful compromise can be as big as possible. Targeted threats are delivered via email (phishing, vishing, etc.), they employ Zero Days and other vulnerabilities to penetrate an information system, and many more. Government and financial organizations are the most frequent targets for this type of cyber threats.
In cyber security, a threat is a possible security violation that can become certainty if the right context, capabilities, actions and events unfold. If a threat becomes reality, it can cause a security breach or additional damages.

Virus hoax
A computer virus hoax is a message that warns about a non-existent computer virus threat. This is usually transmitted via email and tells the recipients to forward it to everyone they know. Computer hoaxes are usually harmless, but their intent is not innocent, since they exploit lack of knowledge, concern or ability to investigate before aking the action describedin the hoax.
A form of phishing attack which takes place over VoIP. In this attack, the attacker uses VoIP systems to be able to call any phone number with no toll-charge expense. The attacker often falsifies their caller-ID in order to trick the victim into believing they are receiving a phone call from a legitimate or trustworthy source such as a bank, retail outlet, law enforcement or charity. The victims do not need to be using VoIP themselves in order to be attacked over their phone system by a vishing attack.
A vulnerability, also known as a security vulnerability, is a flow or error in a software or operating system that can let hackers take control of the affected machine and use it for illegal activities. Vulnerabilities have to solved as soon as they are discovered, before a cyber criminal takes advantage and exploits them.
