Focus on these Areas for a Secure Network Design

Physical Security
You might not chart physical security on a technical diagram, but physical security policy needs to be as specific as possible and communicated broadly – especially when the policy changes.

Organizations should set terms for accessing physical assets (stationary like servers or mobile like cell phones and tablets).
Policy documents should be tailored to those employees that have a need to access the hardware. Non-eligible employees should be alerted by emphasizing consequences for non-compliance.
Technologies that enhance physical security include RFID cards, premium locks, fingerprint reading devices, PIN pads and retinal scanners. Management may need to be advised that the company should not skimp on purchasing quality devices to enhance physical security.
Not to be overlooked: Any physical protection guarding sensitive areas around servers that hold critical business data.

If servers are off-site, the facility should provide documents containing their most recent security audits.
If servers are on site, multiple barriers to entry need to be created to protect data.
Unapproved access to encryption codes, network schemes, IP addresses or administrative user IDs and passwords could have a devastating effect on your company. MSPs and IT providers are encouraged to help their clients truly think through all of these physical components, even if the MSPs rarely visits the physical business location

What is the LM authentication protocol?

The LM authentication protocol, also known as LAN Manager and LANMAN, was invented by IBM and used extensively by Microsoft operating systems prior to NT 4.0. It uses a password encrypting technology that is now considered insecure. LM works by creating a "hash" of your password, as follows: Breaking the password into seven-character chunks: If the password length is not a multiple of seven (i.e., 7, 14, 21, 28...), LM pads the remainder of each chunk with zeroes to make it a full seven bytes long. For example, a ten-letter-long password would be divided into a seven-character-long chunk and a three-character-long one, and the smaller one would have zeroes added to it to push it up to seven characters. Mapping all lowercase letters into uppercase: For example, Dog becomes DOG. Encrypting each chunk: LM uses each chunk as a 56-bit DES (a standardized cipher standard) key to encrypt the following string: KGS!@#$%. Concatenating those strings (i.e., linking them end-to-e
