Computer Security

In the dynamic and interconnected world of technology, computer security stands as the frontline defence against unauthorized access, misuse, theft, and a myriad of security threats that loom in the digital space. As the internet facilitates unprecedented convenience, it also exposes systems to viruses, hacking, and theft, underscoring the critical role of computer security.

Types of Computer Security

1. Cybersecurity

   • Shields computers and networks from cyberattacks when connected to the internet.

2. Information Security

   • Safeguards data confidentiality, integrity, and availability, thwarting theft or unauthorized use.

3. Application Security

   • Ensures the resilience of applications and databases, fortifying against hacks and safeguarding user data.

4. Network Security

   • Guards networks and user information against threats like packet sniffing, spoofing, and man-in-the-middle attacks.

Types of Cyber Attacks

1. Denial of Service Attack (DoS)

   • Overwhelms a network or system with an influx of requests, rendering it temporarily or permanently unavailable.

2. Backdoor Attack

   • Covertly installs malware alongside legitimate software, compromising computer security.

3. Eavesdropping

   • Illegally intercepts network communication, potentially pilfering sensitive information or passwords.

4. Phishing

   • Deceives users into revealing personal information to fraudulent entities and website attackers.

5. Spoofing

   • Impersonates valid identities by falsifying data such as IP addresses or usernames.

6. Malware

   • Malicious software designed to harm computers, encompassing adware, spyware, ransomware, and trojans.

7. Social Engineering

   • Manipulates users' psychology to extract confidential information.

8. Polymorphic Attacks

   • Adopts multiple forms to evade detection, posing a sophisticated challenge to security measures.

In the evolving landscape of computer security, staying vigilant and employing robust measures is paramount. As technology advances, so too must our defences against an ever-growing array of cyber threats. Computer security isn't just a shield; it's a dynamic strategy to ensure the integrity, availability, and confidentiality of digital assets in an interconnected world.
