What is Importance of Computer Security?

Computer security, a broad concept that includes almost any software or hardware designed to prevent the loss or theft of electronic data, is important for a variety of reasons, but perhaps most importantly to keep data safe. The term "computer security" usually refers to the protection of a computer's internal components

What is Importance of Computer Security?

The data and vast amounts of information that most people save on their hard drives are often much more valuable than the machines themselves. In general, the importance of computer security stems from the potential for damage if data is lost.

In these situations, the importance of computer security is evident. It's less obvious for home computer users, but it's just as important.

Core Principles of Cyber Security:-

  • Confidentiality – Sensitive or confidential information should be kept that way, and only authorised users should have access to it.
  • Integrity – Information must not be changed from its original state to maintain its integrity.
  • Availability – When authorised users require information or systems, they must always be available.

Types of security controls:-

Understanding the importance of data and software security will help you formulate a plan to protect that data.

Authentication: in conjunction with authorization, is one of the most recommended methods for improving data security and avoiding data breaches.

Access control: The process of authentication and authorization is known as access control.

Backups & recovery: recuperation Prioritizing data security often necessitates developing a strategy for gaining access to your company's and clients' information in the event of a system failure, catastrophe, data corruption, or breach. Making a copy of your data and storing it on a separate system or medium, such as a tape, disc, or the cloud, is what a data backup entails. Lost data can be retrieved using backup.

Encryption: Data encryption software successfully improves data security by converting plaintext into encrypted cipher text using an algorithm (called a cipher) and an encryption key. The cipher data will be unreadable by an unauthorised person.

Data masking: Data masking software obscures data by using proxy characters to obscure letters and numbers. Behind the masking, the data is still there. Only when an approved user gets the data does the software change it back to its original form.

Tokenization: replaces sensitive data with random characters that are not reversible algorithmically. Rather than being generated and decrypted by a mathematical algorithm, the relationship between the data and its token values is stored in a secure database lookup table (as in the case of encryption). While the actual data is stored on a separate, secure platform, the token representing the real data is used as a substitute across various systems.

Deletions & erasure: When electronic data is no longer required and must be permanently removed from the system, erasure can be used to overwrite the data, rendering it unrecoverable. Erasure is not to be confused with deletion, which is a process that simply hides data in a way that makes it easier to recover.

So, what exactly is "cyber hygiene"?

Cyber hygiene assessment is a set of procedures for dealing with the most common and pervasive data security threats that businesses face. The aim is to prevent data breaches and malware infections by addressing the common root causes of many cyber security incidents.

While the procedures are straightforward, they can be resource-intensive and thankless. However, practising cyber hygiene is worthwhile because it makes it much more difficult for attackers to succeed and reduces the amount of harm they can cause. Once cyber hygiene best practises have been implemented, all you need are daily routines, good employee behaviour, and periodic check-ups to ensure your organization's information systems are in good working order.

Implementing Good Cyber Hygiene:-

The goal for all businesses should be to protect the company with good cyber hygiene and basic lines of defence, as well as to improve response times with more advanced tools and strategies.

  1. Key areas of the organization need to be Identify and prioritized.
  2. Identify the most significant cyber threats you face, as well as their potential impact and response strategies.
  3. Develop and implement an incident response strategy.
  4. Make cyber security education and awareness a priority.
  5. Follow best-practice network construction and monitoring guidelines.
  6. Use access control to reduce risks.
  7. Keep up with the technological advancements and use standardised secure configurations.
  8. Put in place procedures to protect and recover data.
  9. Prevent malware exposures and keep track of them.
  10. Handle cyber risks associated with external dependencies and vendors.
  11. Monitor and remediate cyber threats and vulnerabilities.

Computer security refers to the safeguarding of computers and the data they contain. Computer security measures can range from password protection to firewall configuration—important it's to become familiar with as many as possible to ensure that your data and devices are well protected.
