At the same time, many of these forms of security overlap essential IT functions. For simplicity, this article will look at the holistic approach to basic computer security.

Types of Computer Security

Computer security, also referred to as cyber security, protects computer systems, including hardware, software, networks, and electronic data.

Our goal is to provide a comprehensive look at the many aspects of computer security, including application security, network and internet safety, and data integrity.

1. Application Security

Categories of Application Threats

The following are the most typical types of application risks that are connected to software or applications:

A. Input validation

Properly verifying any input provided by users is known as input validation or data validation. A malicious user attempting to assault software and programmes might be difficult to identify. As a result, it should double-check and verify every piece of data before entering it into the system.

Here’s a list of flaws that might be fixed simply by verifying input.

• Buffer overflow
• SQL injection
• Denial of service (DoS) attack
• Cross-site scripting
• Information disclosure

B. Authorization

Authorization is a security technique for determining a user’s rights or access to system resources, including computer programmes, files, services, data, and application features.

C. Session Management

The web container’s session management procedure secures numerous requests for a service from the same user or organization. Session management may be divided into two categories: cookie-based and URL rewriting.

A web administrator uses session management to monitor the number of visits to an application and movement throughout the site.

Here is a list of some session-related vulnerabilities such as:

• Hijacking session
• Replaying session
• Man in the middle Attack, etc.

D. Parameter Tampering

Malicious hackers use parameter tampering to breach an application by changing the parameters in the URL string.

It’s a direct attack that targets the application’s business logic to change application data, including user passwords and permissions, as well as product prices and quantities.

Example

For example, a shopping site uses hidden fields to refer to its items, as follows:

<input type=”hidden” id=”1001” name=”price” value=”500.00”>

An attacker may reduce the price of a given item by altering its “value” information.

2. Information Security

As a kind of computer protection, IS protects the confidentiality, integrity, and availability of computer systems against unauthorized use, modification, or destruction.

The CIA triangle model for information security ensures data confidentiality, integrity, and availability without impacting productivity, emphasizing information security.

3. Network Security

In computer security, network security refers to preventing and guarding against computer network attacks. There are rules and settings to keep computer networks and data safe while also ensuring that they are accessible to the right people.

Network Security Methods

Increase network security, there are a variety of components or ways. The most common network security components have been discussed in this article.

• Antivirus Software
• Application Security
• Behavioural Analytics
• Data Loss Prevention (DLP)
• Email Security
• Firewalls
• Mobile Device Security
• Network Segmentation
• Security Information and Event Management (SIEM)
• Virtual Private Network (VPN)
• Web Security
• Wireless Security
• Network Access Control (NAC)

4. Endpoint Management Security

Human mistake is a fundamental weakness that cybercriminals may readily exploit. End users are quickly becoming the most dangerous security threat in any firm. On the other hand, the end-user does not fault their own and is primarily a result of a lack of understanding and ICT policy. They have the potential to open the virtual gates to cyber attackers unintentionally.

That is why individuals who have access to sensitive data must have a thorough understanding of comprehensive security rules, procedures, and protocols. It is preferable to equip them with a security awareness training programme that includes the following topics:

• Cyber security and its importance
• Phishing and Social Engineering attack
• Password creation and usage
• Device Security
• Physical Security

5. Internet Access Security

From my experience as a Cybersecurity analyst Internet Access Security is the most effective form of computer security. Internet Access Security can be described as all-encompassing where enforcement happens at the source of the endpoint – blocking all access to the internet. Most internet access security software will require you to develop a comprehensive set of policies to triage your internet traffic.

It is described as developing a set of rules and activities to secure computers linked to the Internet. It’s a kind of computer security that focuses on dangers that originate on the Internet, such as:

A. Hacking

A hacker is someone who looks for flaws in computer systems or networks and exploits them to obtain access. Hacking is a term that describes actions that include using a computer system or a network to get unauthorized access to or control plans for nefarious purposes. There are various forms of computer security used to secure an organization’s information technology infrastructure.

B. Computer Viruses

When a computer virus infects another computer without the user’s consent, it is a malicious computer programme. It has the power to corrupt or harm data, delete files, format hard drives, or render discs unreadable.

Viruses may be classified into the following categories:

• Boot Sector Virus
• Direct Action Virus
• Resident Virus
• Macro Virus
• Multipartite Virus
• File Infector Virus
• Browser Hijacker
• Polymorphic Virus
• Web Scripting Virus

A computer virus may spread on your computer and other devices in the following ways:

• Downloads Software Or Files
• Email Attachments
• Phishing Emails
• External Devices
• Online Advertisements
• Click On Malicious File
• Infected Website
• Copying Data From Infected Computer
• Unsolicited Email
• Social Media Scam Links

C. Denial-of-Service Attacks

Denial of Service (DoS) attacks cause a system to go down, making it unavailable to users. Computer systems, devices, and other resources are inaccessible to ordinary users when an attacker’s intrusion hampers them.

As a consequence of a DoS assault, regular traffic cannot be processed, resulting in a denial of service for the target system’s users.

D.  Malware

Malware is a kind of “malicious software” that usually consists of a software programme or code. Cyber attackers are meant to cause substantial harm to data and computer systems. An email with a link or file attached contains malware, and the user must click on the link or open the file to activate the malware.

Ransomware is one of the most dangerous forms of malware since it can lock users’ computers and steal their data.

Finally, computer security refers to protecting your organization’s software, hardware, and network from harmful attacks. We’ve gone through several methods of computer security. Thank you for reading; I hope it was helpful.
