This article discusses the significance of networks and network security in cybersecurity, describing how networks facilitate communication between devices and the essential functions they provide, such as file and hardware sharing, centralized management, and the importance of security measures to safeguard against cyber threats.
Affected: networks, cybersecurity sector
Affected: networks, cybersecurity sector
Keypoints :
- Networks enable devices to communicate based on established rules.
- They provide functions such as file sharing, hardware sharing, remote access, and centralized management.
- Network security is crucial to protect against data breaches and cyber threats.
- IP addresses and subnet masks help in identifying devices within a network.
- Common network devices include NICs, switches, routers, firewalls, and modems.
- Network architectures define how networks are structured and organized, using protocols and topologies.
- The TCP/IP model is the backbone of modern networking, replacing the OSI model.
- Network services like DNS, DHCP, FTP, and VoIP enable devices to function efficiently across networks.
- Ports are gateways for data communication and require careful management to prevent vulnerabilities.
MITRE Techniques :
- TA0040: **Reconnaissance** – Scanning and probing networks to discover devices and services.
- TA0001: **Initial Access** – Gaining entry into a network through various means (e.g., exploiting open ports).
- TA0002: **Execution** – Running malicious scripts or executables on compromised machines.
- TA0003: **Persistence** – Establishing methods of maintaining access to the network post-initial access.
- TA0004: **Privilege Escalation** – Gaining higher-level permissions for sensitive systems through vulnerabilities.
Indicator of Compromise :
- [IP Address] 192.168.1.10
- [Subnet Mask] 255.255.255.0
- [Domain] google.com
- [Protocol] FTP
- [Protocol] SSH
