Passwords are an important aspect of computer security. A poorly chosen password may result in unauthorized access and/or exploitation of resources of Mitoc Group (the "Company"). All users, including contractors and vendors with access to Company's systems, are responsible for taking the appropriate steps, as outlined below, to select and secure their passwords.
The purpose of this policy is to establish a standard for creation of strong passwords, the protection of those passwords, and the frequency of change.
The scope of this policy includes all personnel who have or are responsible for an account (or any form of access that supports or requires a password) on any system that resides at any Company's facility, has access to Company's network, or stores any non-public Company's information.
This policy applies to employees, contractors, consultants, temporary and other workers at the Company, including all personnel affiliated with third parties. This guideline applies to all passwords including but not limited to user-level accounts, system-level accounts, web accounts, e-mail accounts, screen saver protection, voicemail, and local router logins.
All passwords should meet or exceed the following guidelines
Strong passwords have the following characteristics:
- Contain at least 12 alphanumeric characters.
- Contain both upper and lower case letters.
- Contain at least one number (for example, 0-9).
- Contain at least one special character (for example, !$%^&*()_+|~-={}[]:";'<>?,/).
Poor, or weak, passwords have the following characteristics:
- Contain less than eight characters.
- Can be found in a dictionary, including foreign language, or exist in a language slang, dialect, or jargon.
- Contain personal information such as birthdates, addresses, phone numbers, or names of family members, pets, friends, and fantasy characters.
- Contain work-related information such as building names, system commands, sites, companies, hardware, or software.
- Contain number patterns such as aaabbb, qwerty, zyxwvuts, or 123321.
- Contain common words spelled backward, or preceded or followed by a number (for example, terces, secret1 or 1secret).
- Are some version of "Welcome123" "Password123" "Changeme123"
You should never write down a password. Instead, try to create passwords that you can remember easily. One way to do this is create a password based on a song title, affirmation, or other phrase. For example, the phrase, "This May Be One Way To Remember" could become the password TmB1w2R! or another variation.
(NOTE: Do not use either of these examples as passwords!)
4.2.1 All user-level and system-level passwords must conform to the Password Construction Guidelines.
4.2.2 Users must not use the same password for Company's accounts as for other non-Company's access (for example, personal ISP account, option trading, benefits, and so on).
4.2.3 Where possible, users must not use the same password for various Company's access needs.
4.2.4 User accounts that have system-level privileges granted through group memberships or programs such as sudo must have a unique password from all other accounts held by that user to access system-level privileges.
4.2.5 Where Simple Network Management Protocol (SNMP) is used, the community strings must be defined as something other than the standard defaults of public, private, and system and must be different from the passwords used to log in interactively. SNMP community strings must meet password construction guidelines.
4.3.1 All system-level passwords (for example, root, enable, NT admin, application administration accounts, and so on) must be changed on at least a quarterly basis.
4.3.2 All user-level passwords (for example, email, web, desktop computer, and so on) must be changed at least every six months. The recommended change interval is every four months.
4.3.3 Password cracking or guessing may be performed on a periodic or random basis by the Information Security Team or its delegates. If a password is guessed or cracked during one of these scans, the user will be required to change it to be in compliance with the Password Construction Guidelines.
4.1.1 Passwords must not be shared with anyone. All passwords are to be treated as sensitive, Company's Confidential Information. Corporate Information Security recognizes that legacy applications do not support proxy systems in place. Please refer to the technical reference for additional details.
4.1.2 Passwords must not be inserted into email messages, Alliance cases or other forms of electronic communication.
4.1.3 Passwords must not be revealed over the phone to anyone.
4.1.4 Do not reveal a password on questionnaires or security forms.
4.1.5 Do not hint at the format of a password (for example, "my family name").
4.1.6 Do not share Company's passwords with anyone, including administrative assistants, secretaries, managers, co-workers while on vacation, and family members.
4.1.7 Do not write passwords down and store them anywhere in your office. Do not store passwords in a file on a computer system or mobile devices (phone, tablet) without encryption.
4.1.8 Do not use the "Remember Password" feature of applications (for example, web browsers).
4.1.9 Any user suspecting that his/her password may have been compromised must report the incident and change all passwords.
Application developers must ensure that their programs contain the following security precautions:
4.5.1 Applications must support authentication of individual users, not groups.
4.5.2 Applications must not store passwords in clear text or in any easily reversible form.
4.5.3 Applications must not transmit passwords in clear text over the network.
4.5.4 Applications must provide for some sort of role management, such that one user can take over the functions of another without having to know the other's password.
Passphrases are generally used for public/private key authentication. A public/private key system defines a mathematical relationship between the public key that is known by all, and the private key, that is known only to the user. Without the passphrase to "unlock" the private key, the user cannot gain access.
Passphrases are not the same as passwords. A passphrase is a longer version of a password and is, therefore, more secure. A passphrase is typically composed of multiple words. Because of this, a passphrase is more secure against "dictionary attacks."
A good passphrase is relatively long and contains a combination of upper and lowercase letters and numeric and punctuation characters. An example of a good passphrase:
"The*?#>*@TrafficOnThe101Was*&#!#ThisMorning"
All of the rules above that apply to passwords apply to passphrases.
The Information Security team will verify compliance to this policy through various methods, including but not limited to, periodic walk-thrus, video monitoring, business tool reports, internal and external audits, and feedback to the policy owner.
Any exception to the policy must be approved by the Information Security Team ([email protected]) in advance.
An employee found to have violated this policy may be subject to disciplinary action, up to and including termination of employment.
