Computer Security, Cyber Security or IT Security is the protection of computer systems and networks from the theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.
IT Security covers the several components
- Endpoint Protection (EPP) – Detect malware, ransomware at the workstation and server level
- Mobility Security
- Endpoint Detection and Response (EDR) – Detect and Respond to malware, ransomware at the workstation and server level
- Kaspersky Endpoint Detection and Response
- Perimeter Protection – Network Firewall IDS
- Network Connectivity – VLAN Port Security, Wireless Security
- Mail Server Security Gateway
- Employee Productivity Measurement and Management
- Physical Privacy/Protection
Types of IT Security
Network security is used to prevent unauthorized or malicious users from getting inside your network. This ensures that usability, reliability, and integrity are uncompromised. This type of security is necessary to prevent a hacker from accessing data inside the network. It also prevents them from negatively affecting your users’ ability to access or use the network.
Network security has become increasingly challenging as businesses increase the number of endpoints and migrate services to public cloud.
Internet security involves the protection of information that is sent and received in browsers, as well as network security involving web-based applications. These protections are designed to monitor incoming internet traffic for malware as well as unwanted traffic. This protection may come in the form of firewalls, antimalware, and antispyware.
Endpoint security provides protection at the device level. Devices that may be secured by endpoint security include cell phones, tablets, laptops, and desktop computers. Endpoint security will prevent your devices from accessing malicious networks that may be a threat to your organization. Advance malware protection and device management software are examples of endpoint security.
Applications, data, and identities are moving to the cloud, meaning users are connecting directly to the Internet and are not protected by the traditional security stack. Cloud security can help secure the usage of software-as-a-service (SaaS) applications and the public cloud. A cloud-access security broker (CASB), secure Internet gateway (SIG), and cloud-based unified threat management (UTM) can be used for cloud security.
With application security, applications are specifically coded at the time of their creation to be as secure as possible, to help ensure they are not vulnerable to attacks. This added layer of security involves evaluating the code of an app and identifying the vulnerabilities that may exist within the software.
