Computer security aims to protect computing systems and data from threats. It operates on multiple layers including physical, network, system, application, and user security. The key objectives of computer security are confidentiality, integrity, and availability of systems and data. To be secured, computer security addresses hardware, software, communications, and data. It emphasizes precaution, maintenance, and timely reaction to incidents. Risks to computer security include malware, email, and network attacks as well as identity theft. Computer security faces challenges due to complex algorithms, counterintuitive procedures, and need to consider potential attacks. Awareness of computer security helps minimize attacks and protect information and resources.

Computer Security
• Computer Security is a security that is applied to computing devices for the protection of computing systems and the data that they store and access. • The network environments and network based applications provide more attack paths. • Computer administration and management have become more complex which produces more attack avenues.
Layers of Computer Security • Layer 01: Physical Security – Safeguard the personal, hardware, programs, networks and data from physical threats. • Layer 02: Network Security – Protects the networks and their services from unauthorized modification, destruction or disclosure. • Layer 03: System Security – Protects the system and it’s information from theft, corruption, unauthorized access or misuse. • Layer 04: Application Security – Cover the use of software, hardware and procedural methods to protect applications from external threats. • Layer 05: User Security – Ensure that a valid user is logged in and that user is allowed to use an application.
Key Objectives of Computer Security • Confidentiality – Assures that private or confidential information is not ma de available or disclosure to unauthorized individuals. • Integrity – Assures that information and programs are changed only in a specified and authorized manner and that system performs it’s intended fu nction in an unimpaired manner, free from deliberate. • Availability – Assures that systems work promptly and service is not denied to authorized users.
What to Secure In Computer Security ? • Hardware – Laptops, Desktop, PCs, CPU, Hard disk, Storage devices, etc. • Software – Operating System and Software Applications • Communications – Emails, Instant messengers and browsing activities. • Data – Personal identifications like Identity Numbers, Passwords, Credit Card details, etc.
Fundamental Concepts of Computer Security • Precaution – follow the preventive measures while using computer system and applications. • Maintenance – Managing all the challenges in computer applications and keep them up to date. • Reaction – Act timely when security incidents occur.
Computer Security Risk Attacks • Malware Attacks • Email Attacks • Packet Sniffing • Be an intermediary for another attack • Identity theft and computer frauds
Challenges of Computer Security • Computer security is not as simple as it might first appear to the novice. • Multiple algorithms or protocols may be involved. • Procedures used to provide particular services are often counter intuitive. • Potential attacks on the security features must be considered.
Benefits of Computer Security Awareness • This type of Awareness helps to minimize the chance of computer attacks. • It helps to protect sensitive information and computing resources from unauthorized access. • Helps to prevent loss of information in the system. • It used to protect from cyber criminals from using their systems in order to launch attacks on the other computer systems.
