DHN1 Task 1: Network Merger and Implementation
Company A security and infrastructure problems:
• Network security problems in company A:
o Company A has multiple unnecessary open ports shown in the security
risk analysis. These open ports include ports 21-90 and port 3389.
Several of these ports should be secured or disabled. For example, port
23 is a TCP called Telnet. Telnet is an unsecure protocol that gives
access to remote systems and has several known vulnerabilities. Port
3389 is the Remote Desktop Protocol (RDP) which is used to connect to
computers remotely with a graphical interface. This port should be
昀椀 ltered so that access is limited to only certain users within the
company, as several known vulnerabilities exist.
o Company A has an issue with having very weak password
requirements. The security assessment shows that all current users
use eight-character passwords. If an attacker gains knowledge of this
information, it greatly increases the risk of a password attack and
allows the attacker to gain access to that system. Passwords should
also be mandated to periodically be changed for users.
• Network infrastructure problems in Company A:
o Company A shows that it is currently using the Meraki wireless access
point for its Windows laptops connectivity. This product has several
known vulnerabilities and is also at its End-of-Life, meaning patches for
newly discovered vulnerabilities will not be available from the
manufacturer.
o Company A is showing to have several pieces of equipment in use that
are at the End-of-Life. End-of-life equipment is designated as
equipment that is no longer supported by the vendor. This is a major
