Your Complete Guide To Computer Security Certifications And Career


According to reports from Risk-based security, during the first six months of 2023, there were more than 5,000 breaches reported on 7.9 million data exposed. It was 33.3% higher than in 2023 and records exposed also doubled by 112%.

We live in an Internet-driven world that makes our life comfortable. But at the same time, it poses serious computer security threats that can be nerve-wracking to solve. It sounds like real trouble. So, getting yourself educated on computer security concepts and fundamentals can help you face and solve unexpected threats you encounter at any time. Also, it helps detect the vulnerabilities in your security system and take measures to safeguard your data against cyber-attacks.

Besides, experts suggest that being aware of computer security is a a good way to safeguard your system and data integrity.

The following blog post discusses:

  • What is computer security? (Computer security definition)
  • Types of computer security
  • Why consider learning computer security (cyber security)?
  • What are the career opportunities in computer security?

So, let us get started by briefly understanding the concept of computer security that will enhance our vision to perceive it better in 2023.

Computer Security Definition & Its Types

What is computer security? In simple terms, computer security is safeguarding your system from any unrecognized access, theft, or intrusion. For instance, when you use a firewall, it spots and prevents unauthorized entry into your computer network.

Depending on the purpose, computer security gets categorized into the following types:

  • Information security
  • Network security
  • Application security
  • Internet security
  • Cyber security

Hence, Computer security can be defined as controls that are implemented to ensure the confidentiality, integrity, and availability of all computer components. Now, further elaborate lets learn about security types.

Computer Security Types

There are different kinds of computer security that are widely used to protect an organization's valuable information against the finest cyber threats. Below are the top 5 security types that assist in protecting valuable information.

1. Information security

This popular CIA Triad security model is the starting point of any organization’s security that abides by the three principles - confidentiality, integrity, and availability. It is a traditional security form that has been in existence for several decades.Information security

Confidentiality - This security principle states that only authorized people can access or modify any information or operation. For instance, entering a password while operating your debit cards at any ATM is an authentication to the access of sensitive information that ensures confidentiality. The best countermeasures to retain confidentiality are data encryptions and labeling, good access controls, and powerful authentication mechanisms.

Integrity - Maintains data authenticity and resists any unauthorized data modifications. For instance, the bank software provides data integrity of all transaction records of a user account. The best practices to maintain integrity are digital signatures, encryption, and hashing.

Availability - Any time access to authorized persons. For example, with a debit card and its associated PIN, you have 24/7 access and availability of ATM services. The use of hardware fault-tolerant servers is the best way to maintain the availability principle.

2. Network security

According to Statista, Trojans account for 58% of all computer malware, and as per Cloudflare, there was a 175% increase in DDoS attacks in the fourth quarter of 2023.

This computer security model consists of hardware and software technologies to prevent unauthorized access to the system and network, which helps maintain data integrity and usability.

Some types of network security protections include

  • Next-Generation Firewalls - These have inbuilt security protocols to check the network traffic both ways. The next-gen firewall blocks out not-so-desirable traffic and prevents the possibility of an application layer or a malware attack. 
  • Remote access VPN - It is an effective way to protect the computer network for people accessing it via extranet, mobiles, and telecommuters. Encryption, data scanning, and multi-factor authentication are a few ways to ensure data privacy via VPNs.
  • Zero Trust Network Access (ZTNA) is a standard security method that emphasizes providing the required user access that is enough to perform their job roles. 
  • Data Loss Prevention (DLP) - It is a computer security model that clubs technology and cybersecurity techniques to safeguard any sensitive organization’s data from being exposed.  
  • Cloud-Network Security - It is a popular data center premise that holds and protects tons of data from the applications using a Software-defined Networking/Wide Area Network.

These offer a shield against malware attacks like trojans, virus, worms, trojans, and adware. A small brief on these common cybersecurity threats can help to comprehend better:

Adware - It is a common type of malware displayed on the ad on your laptops and mobiles and does not cause a high degree of danger.

Worms - A self-replicating program that swallows the OS files until all the information on the system gets emptied.

Virus - A piece of infected code/program that attaches itself to another program to procreate multiple times that gets transmitted during a file or a software share.

Trojans - It is malware disguising itself as legit software to pull out sensitive financial information from computers. 

3. Application security

Application security is the process of safeguarding applications from outside security threats by using the related hardware and software design in the development phase. 

With application security, all the malicious activities on the platform get minimized, which helps prevent any data access or modifications by hackers. 

For instance, a firewall installed in a software application determines the file handling and execution procedures, a countermeasure against undefined file executions in that application. As far as hardware is concerned, Routers is the best way to stay invisible with the IP addresses searched for on that particular computer.

Some other instances of application security tools are biometric systems, antivirus software, encryption and decryption programs, and spyware detection programs.

4. Internet security

According to Cybersecurity ventures, there will be a ransomware attack per 11 seconds in 2023, and in comparison to their previous analysis, it is a rise 0f 20% from 2019, which was 14 attacks per second.

To prevent such attacks, Internet security abides by particular protocols to ensure protection from viruses, hacking, malware, and DDoS attacks, i.e when an e-commerce site uses security measures like Multi-factor authentication it signals trustworthiness for its customer base to navigate and engage in a business transaction.

5. Information Technology Security

According to Verizon, 43% of cyber attacks gets aimed at small businesses. But only 14% are ready with a security system.

IT security refers to the activities, processes, and best practices protecting networks, information, or devices from unidentified access.  The three areas that encompass IT security is - cloud security, endpoint security, and cybersecurity.

  • Endpoint security - It is the act of safeguarding all the network endpoints like mobiles, PCs, and laptops from malicious activities.
  • Cybersecurity - It is the process of protecting networks, computers, information, and gadgets against any threats.
  • Cloud security - As the name suggests, it is a set of strategies designed to safeguard the cloud environment against any cyberattack.

As you can witness, whatever the security protocol the companies or individuals deploy, hackers find a loophole to break into your system. Thus, it compels large corporations to hire seasoned computer security professionals to ensure confidentiality and integrity and safeguard their reputations. It, in turn, opens job opportunities for many.

These job opportunities are an ingenious reason to  study cybersecurity and pursue a promising career. Besides, there are some highly-attractive benefits that let you consider cybersecurity as a career option.
