Cookies are stored by websites on a user's device. They are used to track user preferences, session information, and provide a personalized browsing experience.
A Distributed Denial of Service (DDoS) attack inundates a target server or network with excessive traffic originating from numerous sources, making it inaccessible to genuine users.
A security policy comprises a collection of formally documented regulations, recommendations, and protocols that delineate an organization's methods to safeguard its information, assets, and technological resources.
Use secure communication protocols, verify digital certificates, and avoid public Wi-Fi for sensitive transactions. Implementing strong encryption also helps.
A honeypot is a decoy system or network designed to attract attackers. It allows security professionals to study their tactics, techniques, and motivations.
A digital signature employs cryptographic methods to confirm the genuineness and unaltered state of a digital document or message, assuring both the sender's authenticity and the content's integrity.
It involves attackers employing a trial-and-error approach to find a password or encryption key by systematically testing every conceivable combination until they discover the correct one.
Common threats include malware, ransomware, phishing, DDoS attacks, insider threats, and zero-day vulnerabilities.
Patch management regularly applies updates and patches to software and systems to fix security vulnerabilities. It's crucial for preventing the exploitation of known weaknesses by attackers.

PKI is a system of cryptographic techniques that enables secure communication over an insecure network. A public key and a private key pair are employed for various cryptographic operations such as encryption, decryption, the creation of digital signatures, and the validation of public keys through the use of certificate authorities (CAs) to ensure their authenticity.
A strong security policy includes elements like access control, encryption, regular updates, user training, incident response plans, and compliance with relevant regulations.
A rootkit is malicious software that gives attackers unauthorized access to a computer or network. Detection involves using specialized anti-rootkit tools and monitoring for suspicious system behavior.
XSS involves injecting malicious scripts into web applications, which can compromise user data. SQL Injection exploits vulnerabilities in SQL queries to manipulate a database. Both are forms of web application vulnerabilities.
It refers to a security vulnerability present in software or hardware that is undisclosed to the vendor and lacks an existing solution. This loophole can be leveraged by malicious actors before a remedy is created.
It is a framework for information security management systems (ISMS), while ISO 27002 provides guidelines for implementing security controls and practices within an organization.
Threat detection systems monitor network traffic and system logs to identify suspicious activities or potential security threats using predefined rules and machine learning algorithms.
Ethical hacking involves testing systems and networks for vulnerabilities to strengthen security. Principles include obtaining proper authorization, maintaining confidentiality, and responsible disclosure of findings.
Network security includes perimeter security, firewall protection, intrusion detection systems, VPNs, and network segmentation to safeguard data and resources.
Risk assessment in cybersecurity involves identifying, assessing, and prioritizing potential threats and vulnerabilities to make informed decisions on security measures.

Incident response encompasses a methodical strategy for handling and diminishing security incidents, encompassing key phases such as preparation, detection, containment, eradication, recovery, and knowledge acquisition.
The Least Privilege principle limits the access of users and processes to the bare minimum required for their specific tasks, thereby minimizing the potential for unauthorized actions.
SSL protocol ensures secure data transmission between web browsers and servers using encryption, authentication, and data integrity checks.
Network sniffing is the practice of intercepting and analyzing network traffic to gather information, potentially for malicious purposes. It can be used for monitoring or attacks.
Disaster recovery planning encompasses the proactive preparation and responsive actions required to safeguard against data loss or system failures, ultimately ensuring the uninterrupted operation of a business.
SIEM systems gather, correlate, and scrutinize security-relevant data from diverse origins to identify and react to security events.
Cryptographic keys should be securely generated, stored, rotated, and protected to maintain the confidentiality and integrity of encrypted data.
Common methods include data shredding, overwriting, degaussing, and physical destruction to ensure that sensitive information cannot be recovered from storage media.
Endpoint security focuses on securing individual devices (endpoints) like computers and mobile devices by using antivirus, anti-malware, and intrusion detection systems.
AI is used for threat detection, pattern recognition, and anomaly detection to improve cybersecurity defenses and automate incident response.
Challenges include data breaches, compliance, data loss prevention, and securing shared responsibility models in cloud environments.
Penetration testing replicates real-world attack scenarios to discover vulnerabilities, whereas vulnerability assessments concentrate on scanning systems to detect recognized weaknesses.
SOC is a centralized team responsible for real-time monitoring, detecting, and responding to security incidents.
Compliance ensures that an organization follows relevant laws and regulations, helping protect data and avoid legal consequences.
MFA bolsters security by necessitating users to furnish multiple authentication factors, typically a combination of something they possess (e.g., a mobile token) and something they are aware of (e.g., a password).

APTs are long-term, targeted cyberattacks by skilled adversaries. They use stealth, persistence, and sophisticated techniques to breach systems.
Blockchain can enhance security through decentralized consensus, data integrity, and immutable records. It's used in secure transactions and identity management.
Employ segmentation, strong access controls, regular audits, and network monitoring to protect against threats across a vast network.
Forensics helps investigate incidents, gather evidence, and understand attack vectors, aiding in incident response and legal actions.
Secure protocols are essential for data confidentiality and integrity. Use encryption and authentication, and keep protocols updated to mitigate risks.
Implement security into the development pipeline with automation, continuous monitoring, and collaboration between development and security teams.
Micro-segmentation isolates network segments for finer control and security. It limits the lateral movement of threats within a network.
