- A firewall controls inbound and outbound traffic across networks, and monitors contact attempts leading to the network; to decide to allow login or block communication, using predetermined security rules. Network security relies heavily on walls, especially next-generation security walls, which focus on blocking malware and application-layer attacks.
- Network partitioning is an architectural approach that divides the network into multiple sectors or mini sub-grids, each of which functions as its own mini-grid. Network partitioning is very important in network security, it will allow network managers in institutions to control and monitor the flow of traffic between subgrids.
- Network Access Control (NAC) is a computer network solution that uses a set of protocols to determine and implement a policy that describes how to secure a network contract by devices when first attempting to access the network, the NAC system also uses MAC address control and SNMP protocol to deny network access to non-agreement devices, place in an isolated zone or grant only limited access to computing resources, thus preventing insecure network damage contract.
- The virtual private network, or also known as VPN, provides an encrypted online call from a device to a network, and this encrypted communication contributes to the secure transfer of sensitive data over the network, as well as allows users to work remotely with their organizations, as it ensures that they prevent touch traffic by unauthorized persons.
- Email Security refers to any processes, products and services designed to protect email accounts, and email content is secure from external threats. It is important for organizations to implement email security to protect against many forms of email cyber-attacks, in addition to ensuring that sensitive messages are encrypted as they move from the network to the recipient.
- Data Loss Prevention (DLP) is a cybersecurity approach that combines technology and best practices to prevent the exposure of sensitive information to any external threat to the organization, especially sensitive data such as Personally Identifiable Information (PII) and compliance-related data: HIPAA, SOX, PCI DSS, etc
- IPS/IDS are important parts of a company's security infrastructure, where one device can detect and report an attack, while the other can stop attacks based on security policies. The main difference between them is that IDS is a monitoring system while IPS is a control system. IDS does not change network packets in any way, while IPS prevents the packet from being delivered based on the contents of the packet.
- Endpoint Detection and Response (EDR) are defined as solutions that record and store system-level behavior, use different data analysis techniques to detect suspicious system behavior, provide contextual information, prevent malicious activity and provide treatment suggestions to restore damaged systems.
- The anti-virus program is one of the programs that can be used to detect malicious activity.
