What is IT Security?
IT security refers to a set of techniques used to protect the integrity of networks, programs and data from attack, damage or unauthorized access. From a computing point of view, security comprises cybersecurity and physical security — both are used by enterprises to protect against unauthorized access to data centers and other computerized systems. Information security, which is designed to maintain the confidentiality, integrity, and availability of data, is a subset of IT security. The use of IT security can help prevent cyber attacks, data breaches, and identity theft and can aid in risk management.
So when talking about IT security, one might wonder “What are we trying to protect ourselves against?” Well, there are three main aspects we are trying to control, name:
- Unauthorised Access
- Unauthorised Deletion
- Unauthorised Modification
These three terms are synonymous with the very commonly known CIA triad which stands for Confidentiality, Integrity, and Availability. The CIA triad is also commonly referred to as the three pillars of security and most of the security policies of an organization are built on these three principles.
Types Of Cyber Attacks
Why is cybersecurity important?
We live in a digital era which understands that our private information is more vulnerable than ever before. We all live in a world which is networked together, from internet banking to government infrastructure, where data is stored on computers and other devices. A portion of that data can be sensitive information, whether that be intellectual property, financial data, personal information, or other types of data for which unauthorized access or exposure could have negative consequences.
Cyber-attack is now an international concern and has given many concerns that hacks and other security attacks could endanger the global economy. Organizations transmit sensitive data across networks and to other devices in the course of doing businesses, and cybersecurity describes to protect that information and the systems used to process or store it.
As the volume of cyber-attacks grows, companies and organizations, especially those that deal information related to national security, health, or financial records, need to take steps to protect their sensitive business and personal information.
How to help protect against cyber security attacks
Follow these steps for cyber safety.
- Only use trusted sites when providing your personal information. A good rule of thumb is to check the URL. If the site includes “https://,” then it’s a secure site. If the URL includes “http://,” — note the missing “s” — avoid entering sensitive information like your credit card data or Social Security number.
- Don’t open email attachments or click links in emails from unknown sources. One of the most common ways people are attacked is through emails disguised as being sent by someone you trust.
- Always keep your devices updated. Software updates contain important patches to fix security issues. Cyberattackers thrive on outdated devices because they don’t have the most current security software.
- Back up your files regularly to prevent cyber security attacks. If you need to wipe your device clean due to a cyberattack, it will help to have your files stored in a safe, separate place.
