This document discusses cyber security and the need for it. It defines cyber security as protecting online information from threats. Major security problems discussed include viruses, hackers, malware, Trojan horses, and password cracking. It provides information on each of these threats and recommends solutions like installing security software, using strong passwords, firewalls, and being aware of social engineering. The conclusion emphasizes that cyber security is everyone's responsibility.

Brute force attacks try a large number of password combinations to gain unauthorized access to a system. For a 2 character password, there are 3,844 possible guesses using letters, numbers, and case variations. While brute force attacks have a high chance of success due to trying many options, they are also hardware intensive and can take a long time. To prevent brute force cracking, users should make long, random passwords using a variety of characters that are not based on personal details.

Network security involves protecting network usability and integrity through hardware and software technologies. It addresses vulnerabilities that threats may exploit to launch attacks. Common vulnerabilities include issues with technologies, configurations, and security policies. Threats aim to take advantage of vulnerabilities and can be structured, unstructured, internal, or external. Common attacks include reconnaissance to gather information, unauthorized access attempts, denial-of-service to disrupt availability, and use of malicious code like worms, viruses, and Trojan horses.

Network security involves protecting a network and its data through hardware and software that manages access and blocks threats. It combines multiple layers of defenses at the edge and within the network, implementing policies and controls to authorize access for users while blocking malicious actors. Network security protects proprietary information, reputation, and allows organizations to securely deliver digital services that customers and employees demand. It utilizes various technologies including access control, antivirus software, firewalls, intrusion prevention, and more.

The document discusses the importance of network security and outlines common security threats such as viruses, hackers, and data theft. It then describes methods for securing a network, including user authentication, firewalls, antivirus software, and encryption. Servers are central to networks for storing data, and securing the server room is crucial, requiring physical access controls, monitoring, locking server racks, and preventing environmental risks like fire or flooding.

End users face common cybersecurity threats such as phishing attacks, ransomware, password reuse, using unpatched devices, lack of remote security, data leakage via social media, and disabling security controls. Key security measures for end users include setting administrator privileges, downloading and installing security updates, installing antivirus software, activating firewalls, using multi-factor authentication, and creating regular backups. Security awareness is important for end users to avoid risks to company assets from security lapses.

The term cyber security is used to refer to the security offered through on-line services to protect your online information. With an increasing amount of people getting connected to Internet, the security threats that cause massive harm are increasing also.
