A Brief Overview of Computer Security

computer security

What is computer security? Also known as information technology security (ITS), this field protects computer systems, networks, and information from breaches. It also works to protect the services that these computer systems provide. Generally, IT security involves implementing various methods to detect, prevent, and recover from a computer system breach. Below, we've provided a brief overview of computer security. Interested in learning more? Read on! Listed below are some common threats to computer security.

Threats to computer security

A few types of threats to computer security are malware, phishing attacks, viruses, adware, and rootkits. Many of these attacks are harmful, and can cause extensive damage to a computer system. Some even allow criminals to gain complete access to your system. Once an infected computer is infected, it can become part of a zombie network used by hackers to attack servers, send spam, harvest confidential information, and spread new viruses.

Another type of threat is the distributed denial of service attack, which involves multiple computers being attacked simultaneously. This type of attack is similar to piggybacking, where one unauthorized user opens a protected door for another. Some threats to computer security also include malicious software known as grayware, which can cause problems for computers by installing and changing software. Most of these programs will pop up windows and gather information without the user's knowledge.

While malicious software is an extremely serious threat, most of these attacks are caused by inside jobs. A major majority of companies attribute these breaches to disgruntled employees. The second largest group of perpetrators, according to corporate security managers, are outside hackers. A large number of companies blame foreign governments or domestic competitors for computer security breaches, which isn't necessarily the case. This makes security measures even more crucial. But these methods aren't enough to stop hackers.

Common methods of preventing a breach

Data breaches can occur from within an organization as well. Insiders can install viruses, spyware, or malware. And they can cause just as much damage as outsiders. The FBI learned this lesson with the unmasking of insider Robert Philip Hanssen in 2001. So insiders should be kept in mind when building computer security strategies. Here are some common methods for preventing data breaches from inside an organization.

The best way to prevent a security breach is to establish a comprehensive IT security management plan that includes managed antivirus, endpoint security software, and firewall management. You should also have policies in place for mobile devices and bring your own device (BYOD).

Training employees is an effective way to prevent a breach. Intruders often target small businesses because employees are direct paths into the system. By training your employees on basic internet usage best practices, you can minimize the risk of a cyberattack. As an employee, you should limit the websites employees can access. This way, they don't accidentally click on malicious links. And, finally, you should consider securing your network and data.

Keeping your passwords strong is crucial. If you've ever forgotten a password, it's easy for someone to access your data. By maintaining a strong password, you can minimize the risks of a data breach and survive the attack. A good password is more secure than a weak one. A strong password is one that combines upper and lower case letters, numbers, and symbols. This means it's much more difficult for hackers to guess and break. You can use a Password Manager to store these strong passwords.

Careers in computer security

There are numerous career options available for those interested in a career in computer security. Computers have become an indispensable part of today's work environment, and as a result, careers in this field are growing as quickly as the technology itself. Getting an education in computer security is an excellent choice for people who are interested in a career that uses the latest technology and security tools. To get started on a career in computer security, a 6-month diploma, one-year certificate, or two-year associate's degree will be enough. Getting a higher education will improve your chances of landing a rewarding position as well.

To become an information security professional, you can either get an undergraduate degree in a STEM field, or another technical degree. You can also pursue a postgraduate degree in information security or penetration testing. Continuing education is essential throughout your career, as security technologies are constantly changing. Not every company can afford an in-house IT security team, so many outsource the security of their information technology to MSPs. Alternatively, you can choose to take a self-study course.

If you are interested in a career in computer security, you can choose to take the CompTIA Security+ certification, which validates the basic security operations. These certificates are useful first impressions in the competitive world of IT security, and employers often favor candidates with this certification. It's also beneficial to take a look at the National Cyber Security Centre, which is the UK's go-to resource on security threats. There are also NCSC-certified Bachelor's degrees and Master's degrees. In addition, you can participate in the Cyber Security Challenge UK, a not-for-profit organisation.
