Computer security, or cyber security, refers to the defense of computerized hardware, software, networks, as well as information contained within these systems, against theft, destruction, or unauthorized disclosure. It encompasses a wide variety of technologies, processes, and practices that are designed to protect information and information systems.
Who is the father of computer security?
The nickname of ‘the Father of Computer Security‘ is usually given to Gene Spafford, an accomplished computer scientist and a professor at Purdue University, but that is not the only reason he is considered a leader. His contribution to computer security has been significant, especially in efforts related to intrusion detection and response, system weaknesses, and cybersecurity strategies. He has written and edited many successful books and articles related to these subjects, which many can say that he did reach to a certain degree. He was also instrumental in the founding of the Computer Emergency Response Team (CERT) at Carnegie Mellon University, which served in the development of many organizational frameworks around the issues and responses to computer security breaches. Many modern cybersecurity concepts are based on his work.
“Importance of Computer Security”:
1. Protects Sensitive Data
Restricts illegal access to information pertaining to women, their finances, and business details.
2. Prevents Cyberattacks
Provides protection from hacking, malware, ransomware, and other harmful threats.
3. Maintains Privacy
Guarantees the privacy of both sensitive information and data associated with an organization.
4. Secures Critical Infrastructure
Safeguards critical infrastructure such as electricity, health services, and mobility from being compromised by cyber criminals.
5. Ensures Business Continuity
Minimizes business interruptions caused by targeted attacks on the organization.
6. Ensures Compliance
Helps organizations meet the legal and regulatory demands of data protection.
7. Protects National Security
Protects from cyber threats capable of endangering the national security of the government and military systems.
8. Builds Trust
Encourages client trust by showing the dedication to data security.
9. Reduces Financial Losses
Reduces the cost implications of cyber crimes, skimming, and misappropriation.
10. Adapts to Emerging Threats
Maintains current security systems and deploys new ones in order to mitigate novel and existing cyber threats.
What are types of computer security?
1. Network Security
Utilizes protection measures safeguarding data in transit employing firewalls, encryption, and VPNs from unapproved access.
2. Information Security (Data Security)
Employs encryption techniques, access control policies, and backup solutions to protect sensitive data while standing still or also in motion.
3. Application Security
Secure programming, threat assessments, and updates are some of the tools used to make the program more robust against potential threats.
4. Endpoint Security
Implements measures that safeguard devices such as laptops and smartphones against potential threats by utilizing antivirus software and endpoint detection systems.
5. Cloud Security
Protects applications and data in the cloud, relying on architectural solutions such as encryptions, secure Application Programming Interfaces (APIs), and multi-factor authentication methods.
6. Identity and Access Management (IAM)
Employs various techniques for restricting access to the system from intruders, such as passwords or biometrics, by controlling the entry of users.
7. Physical Security
Restricts physical threats (such as stealing, and spiking) of hardware by employing locks and even CCTV.
8. Operational Security (OPSEC)
Safeguards critical doing-business processes from potential threats and regulates the level of data abuse in the course of execution.
9. Disaster Recovery & Business Continuity
Guarantees that system and data functions are recovered simply but adequately after any cyber incursion or an external disruptive event employing backups and recovery strategies.
Example of Security: Password Protection
A frequent illustration of security is the restriction of access to online accounts by use of passwords.
For example, setting a password for an email address or a banking application restricts unforeseen access to personal information. As well as employing strong passwords, the incorporation of multi-factor authentication (MFA) protects even further by averting access by any other individual other than the intended user.
Facilitates the speedy recovery of vital systems and information following criminal activities or disasters through the use of backup and business continuity strategies.
