What Is Computer Security?

Computer security is the umbrella moniker under which different types of computer-related security find cover. Computer security, according to Britannica, protects computer systems and information from harm, theft, and unauthorized use. Serial numbers, doors and locks, and alarms are commonly used to protect computer hardware, as they are for other valuable or sensitive equipment. On the other hand, information and system access are protected using various tactics, some of which are pretty complex.

There are 4 types of computer security:

1. Cyber Security
2. Information Security
3. Application Security
4. Network Security

Core Principles of Computer Security:

1. Availability: Information and systems must always be available to authorized users when required.
2. Integrity: Information must not be altered from its original state to retain its integrity.
3. Confidentiality: Sensitive or confidential information must be kept private and accessible only to authorized users.

Why Is Computer Security Important?

Computer security is essentially the protection and preservation of computing systems and their information. It is vital for various reasons, such as:

1. For preserving company assets - Company assets include information stored in computer networks, which is just as important and valuable as the company's physical assets.
2. To comply with governing requirements and moral responsibilities, each organization develops policies and procedures that address the organization's security needs.
3. To gain a competitive advantage - Financial services and e-commerce place a premium on network security.
4. To aid in the reduction of the increasing volume and sophistication of cyber security threats - Threats of this type include targeted phishing scams, data theft, and the exploitation of other network vulnerabilities.

In addition, it aids in the execution of essential business processes and protects confidential and sensitive data. However, only 10% of security safeguards are technical. The remaining 90% depends on good computing practices followed by users.

Can I Learn About Computer Security Online?

Yes, learning about computer security through an online computer security course is a great option. Online courses for computer security are flexible and accommodating, often offered by renowned global schools. One of the essential skills that every computer science student should have is knowledge of computer security. People with a good understanding of computer security have a better chance of securing a position in their desired role, increasing their employability.

With so many computer security positions available, having the right skills can help you land the desired job. Begin developing your technical and workplace skills through online courses, boot camps, or self-study to prepare for a cybersecurity role.

Essential Skills for Computer Security:

According to a study by Burning Glass on computer security hiring, more than half of all computer security job postings require at least one certification. Unfortunately, there are over 300 different certifications, and the quality isn't always consistent. If you're new to cybersecurity, consider starting with a more basic certification, such as the CompTIA Security+. Then, you can begin gaining the work experience required to earn more advanced certifications.
