WHAT IS COMPUTER SECURITY?

Computer security, cybersecurity, or information technology security is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide

Computer security is the protection that is set up for computer systems and keeps critical information from unauthorized access, theft, or misuse. There are various practices in place that are widely in use, mainly for the protection of computer systems and networks and preventing potential malicious activities.

While computer hardware is secured in the same way that sensitive equipment such as lockers and doors are protected, critical information and system access and authorization, on the other hand, are protected through complex security tactics and practices

Types of Computer Security

In this post, we will focus on the different types of computer security such as  application security, network security, internet security, data security, information security and end user security.

  • Application Security.

Common cyber security measures

Guide

Businesses should use different cyber security measures to keep their business data, their cashflow and their customers safe online. These measures should aim to prevent risks from various sources, including:

  • internet-borne attacks, eg spyware or malware
  • user generated weaknesses, eg easily guessed password or misplaced information
  • inherent system or software flaws and vulnerabilities
  • subvert system or software features

Essential cyber security measures

The following processes and tools are fairly easy to introduce, even for the smallest businesses. Combined, these will give you a basic level security against the most common IT risks.

Use strong passwords
Strong passwords are vital to good online security. Make your password difficult to guess by:

  • using a combination of capital and lower-case letters, numbers and symbols
  • making it between eight and 12 characters long
  • avoiding the use of personal data
  • changing it regularly
  • never using it for multiple accounts
  • using two factor authentication

Create a password policy for your business to help staff follow security best practice. Look into different technology solutions to enforce your password policy, eg scheduled password reset. Find different password strategies that could boost your business security.

Control access
Make sure that individuals can only access data and services for which they are authorised. For example, you can:

  • control physical access to premises and computers network
  • restrict access to unauthorised users
  • limit access to data or services through application controls
  • restrict what can be copied from the system and saved to storage devices
  • limit sending and receiving of certain types of email attachments

Modern operating systems and network software will help you to achieve most of this, but you will need to manage the registration of users and user authentication systems – eg passwords. Read more about identity and access management controls.

Put up a firewall
Firewalls are effectively gatekeepers between your computer and the internet, and one of the major barriers to prevent the spread of cyber threats such as viruses and malware. Make sure that you set up your firewall devices properly, and check them regularly to ensure they have the latest software/firmware updates installed, or they may not be fully effective. Read more about firewalls in server security

Use security software
You should use security software, such as anti-spyware, anti-malware and anti-virus programs, to help detect and remove malicious code if it slips into your network. Discover how to detect spam,malware and virus attack

Update programs and systems regularly
Updates contain vital security upgrades that help protect against known bugs and vulnerabilities. Make sure that you keep your software and devices up-to-date to avoid falling prey to criminals.

Monitor for intrusion
You can use intrusion detectors to monitor system and unusual network activity. If a detection system suspects a potential security breach, it can generate an alarm, such as an email alert, based upon the type of activity it has identified. See more on computer security breach detection.

 BENEFITS OF COMPUTER AND CYBER SECURITY

WHAT ARE THE BENEFITS OF CYBER SECURITY FOR YOUR BUSINESS?

  • Protection for your business – cyber security solutions provide digital protection to your business that will ensure your employees aren’t at risk from potential threats such as Adware and Ransomware.
  • Increased productivity – viruses can slow down computers to a crawl, and making work practically impossible. Effective cyber security eliminates this possibility, maximising your business’ potential output.
  • Inspires customer confidence – If you can prove that your business is effectively protected against all kinds of cyber breaches, you can inspire trust in your customers that their personal data will not be compromised.
  • Protection for your customers – ensuring that your business is secure from cyber threats will also help to protect your customers, who could be susceptible to a cyber breach by proxy.
  • Stops your website from going down – if you are business that hosts your own website, a potential cyber breach could be disastrous. If your system becomes infected, it’s possible that your website could be forced to close meaning you will lose money as a result from lost transactions.
