Cisco Port Security Basics and configurations
Today I am going to talk about the Switching topic and that topic is Port Security. Port security is required in the case you want to control the traffic by allowing Specific MAC address entries, which means if the invalid MAC addresses traffic comes, it will be blocked or dropped.
Lets talk about the port security and the modes of port security. So the question is why port security required, may be want to safe from the attacks as well.
Why Port Security is important ?
Well port security is generally used so that you can easily prevent the unwanted MAC address traffic from the external or the internal network.
Port security can be enabled in three different ways are defined as below:

Why Port Security is important ?
Well port security is generally used so that you can easily prevent the unwanted MAC address traffic from the external or the internal network.
Port security can be enabled in three different ways are defined as below:
- Protect : In the protected state, switch port will drops packets with unknown source addresses until you remove a sufficient number of secure MAC addresses to drop below the maximum value.
- Restrict : In the restrict state, switch port will drops packets with unknown source addresses until you remove a sufficient number of secure MAC addresses to drop below the maximum value and causes the SecurityViolation counter to increment
- Shutdown : In the shutdown state, switch port will Continue reading

VMware NSX Achieves Common Criteria EAL 2+ Certification
VMware NSX 6.3 for vSphere has achieved Common Criteria certification at the Evaluation Assurance Level (EAL) 2+ (view the certification report)(view the press release). This marks yet another milestone of our commitment to providing industry leading certified solutions for customers from federal departments and agencies, international governments and agencies, and other highly regulated industries and sectors. Along with FIPS, DISA-STIG, ICSA Labs firewall certification, and several other independent evaluations, the Common Criteria compliance accreditation validates NSX as a reliable network virtualization platform that satisfies stringent government security standards.
Common Criteria is an international set of guidelines (ISO-15408) that provides a methodology framework for evaluating security features and capabilities of Information Technology (IT) security products. It is mutually recognized by 26 member nations.
Regulatory compliance is one of the challenges faced by government IT departments in their efforts to modernize legacy systems, and Common Criteria is often required for procurement sales. The Common Criteria accreditation affirms that NSX for vSphere complies with the security requirements specified within the designated level and simplifies the introduction of NSX into government and highly regulated environments. NSX enables customers in the public sector to implement network Continue reading
