How to mitigate unauthorized access to network infrastructure?
Adversaries can use compromised privileges to traverse a network, expand access, and take full control of the infrastructure backbone. Organizations can mitigate unauthorized infrastructure access by implementing secure access policies and procedures. Implement multi-factor authentication (MFA).
What are CISA recommendations for securing network infrastructure?
The Cybersecurity and Infrastructure Security Agency (CISA) encourages users and network administrators to implement the following recommendations to better secure their network infrastructure: Segment and segregate networks and functions. Limit unnecessary lateral communications. Harden network devices. Secure access to infrastructure devices.
How are network communications protected in Microsoft Teams?
Network communications in Teams are encrypted by default. By requiring all servers to use certificates and by using OAUTH, TLS, Secure Real-Time Transport Protocol (SRTP), all Teams data is protected on the network. This section identifies the more common threats to the security of the Teams Service and how Microsoft mitigates each threat.
What do you need to know about securing a network?
Segment and segregate networks and functions. Limit unnecessary lateral communications. Harden network devices. Secure access to infrastructure devices. Perform out-of-band (OoB) network management.
What are the best practices for securing microservices?
Although securing microservices are harder than monolithic applications, you can protect them effectively by establishing a good strategy and following the best practices. Ideally, the architecture requires a distributed approach that should cover all the different components. Protecting applications, microservices, and users
How to secure network infrastructure devices [ CISA ]?
Disable unnecessary services (e.g., discovery protocols, source routing, Hypertext Transfer Protocol [HTTP], Simple Network Management Protocol [SNMP], Bootstrap Protocol). Use SNMPv3 (or subsequent version), but do not use SNMP community strings. Secure access to the console, auxiliary, and virtual terminal lines.
How is virtual separation used in network security?
Virtual separation is the logical isolation of networks on the same physical network. Virtual segmentation uses the same design principles as physical segmentation but requires no additional hardware. Existing technologies can be used to prevent an intruder from breaching other internal network segments.
