Brute-force Attack

A Firewall is a tool for securing a computer or network environment. It acts as a barrier between the internal and external networks, preventing malicious traffic from entering the network while allowing legitimate traffic to pass through. Firewalls are used to protect valuable data from unauthorized access, detect and prevent attacks, and ensure that only approved users can access restricted areas. Firewalls use various technologies such as packet filtering, application gateway security, URL filtering, etc., to monitor and control incoming and outgoing network traffic. To use a firewall effectively, it must be properly configured according to the specific needs of the organization.

Remote Desktop Protocol (RDP) is an encrypted protocol used to access remote computers or networks securely. It enables users to remotely control and manage a computer from a different location, as if they were physically present in front of the machine. RDP works by authenticating the user with public keys and sending encrypted commands across a network that can only be decrypted with the corresponding private key on the remote computer or server. RDP is commonly used for secure remote access, secure file transfer, and virtual desktop infrastructure (VDI). In terms of cyber security, RDP is one of the most reliable protocols for ensuring data confidentiality and integrity during remote access sessions.

802.1x Access Control List (ACL) is a security protocol that enables secure access to networks, devices and applications. It is used to control access by allowing or denying certain types of traffic at the user level. ACLs can be used to identify, authenticate and authorize users, allowing them access only to specific resources they are authorized to use. It helps protect against unauthorized access, data theft and malicious activity on networks. Use of 802.1x ACL provides an extra layer of protection for data and resources within a network environment.

Mandatory Access Control (MAC) is a type of access control system that limits access to resources based on security labels. It is used in many different types of organizations and for many cyber security purposes. MAC works by assigning each user a specific label, or clearance level, that determines what data they can view or modify. Access to sensitive information like financial records or customer data is limited to those with the highest clearance levels, while access to less important information is made available to everybody. By setting up these levels of security, organizations can ensure that only authorized users are granted access to sensitive information, providing them with increased security and protection from malicious attacks.

Phishing is a form of social engineering attack used to steal personal information and data. It is typically done by posing as a trusted source and sending malicious links or emails that appear to come from legitimate sources. Attackers usually use phishing techniques to gain access to passwords, credit card numbers, and other sensitive data. Phishing attacks can also be used for financial gain or to spread malware. Cyber security professionals must understand the common types of phishing scams, such as deceptive emails, clone websites, and malicious pop-ups, in order to protect against them. Organizations should also provide awareness training to their employees so they know what to look out for when it comes to phishing attempts. By staying vigilant and taking proactive measures against these threats, companies can reduce the risk of falling victim to a successful phishing attack.
