What is it? Vulnerability assessment or vulnerability management is a process of analyzing an organization's systems for possible security flaws. It runs a vulnerability analysis to see if the organization is vulnerable to known vulnerabilities, provides a severity level to those vulnerabilities, and suggests if the danger should be mitigated or remediated. Vulnerability testing aids organizations in determining whether their systems and software have insecure default settings, such as admin passwords that are easily guessable. It also checks for a potential escalation of user rights or faulty authentication procedures, as well as vulnerability to code injection attacks such as SQL injection (SQLi) and cross-site scripting (XSS).  fortinet.com/resources Types of Vulnerability Assessments The following are the most prevalent types of vulnerability assessments used by businesses: Network scan: Identifies susceptible systems on an organization's wired and wireless networks that c

  This lab explores basic configurations to practice routing, switching, and trunking, we practice in this some known networking concepts like DHCP agent relay, VTP domains, 802.1Q encapsulation you can download the lab at  thekeithbarker.com  under the name "Cisco PT DHCP, Routing, Switching 2020-04-07"  extract the files, open the ".pkt" file and follow along with me  Lab Objective:   PCs 1,3 in VLAN 10, Subnet 10.16.0.0 /24 PCs 2,4 in VLAN 20, Subnet 172.16.0.0/24 DHCP assigned addresses for PCs DHCP/Web server in VLAN 777, Subnet 192.168.1.0/24, using .100 Default G/W is .1 in each subnet Verify if clients can ping each other Verify if clients can open the web page of the server at TheKeithBarker.com First configuration on our switches configuration terminal no ip domain-lookup line console 0  logging synchronous no exec-timeout privilege level 15 spanning-tree mode rapid-pvst spann portfast default end  write Create trunks & VTP domain  Sw1 conf t vtp domai

L2 Switching & VLANs Lab troubleshooting

  This lab explores basic configurations to practice VLANs and switching concepts you can download the lab from  thekeithbarker.com  under the name "Cisco PT Layer 2 Switching and VLANs"  then extract the files, open the ".pkt" file and follow along with me  Lab Objective:  use the laptop to open the web page on the Server at 10.67.83.35 Use VLAN 10 for the Laptop and Server. VLAN 10 is supporting the IPv4 network of 10.67.83.32 /27 Assumptions: Trunking is already configured between switches. DHCP services are already enabled for VLAN 10. Let's start  Laptop: when you enter the Laptop configuration you notice that it is not powered on enter the Laptop's physical configurations and click on the power button after that, you notice the appearance of the wifi signals and the APIPA IP address which mean that it is not connected to the DHCP server    Switch 3 show vlan brief there's a vlan 10 and port fa0/2 is part of it show interface fa0/2 switchport fa0/2
