Policy Statement 1.1 In order to strengthen the security and confidentiality of information, the Council has established specific requirements for protecting information and information systems against unauthorised access. 2. Purpose 2.1 Information security is the protection of information against accidental or malicious disclosure, modification or destruction. Information is an important, valuable asset of Calderdale Council which must be managed with care. All information has a value to the Council.

4 Network Password Management Policy & Procedures Page: 3 of The management and security of passwords is an important element in protecting against the unauthorised access to Council Information systems. 2.4 The purpose of this policy is to establish a standard for the creation of strong passwords, the protection of those passwords, and the frequency of change. 3. Scope 3.1 Passwords are used to protect all information systems. Users must be aware that all system authentication credentials assigned to them are for their own use. Authentication credentials must not be shared or disclosed to any third party, other than authorised system support personnel. 3.2 This policy applies to all Councillors, Committees, Departments, Partners, Council employees, contractual third parties and agents of the Council who use Calderdale Council provided ICT facilities and equipment, or have access to, or custody of, Calderdale Council information All users must understand and adopt/use this policy and are responsible for ensuring the safety and security of the Council s systems, information and data that they use. 3.4 All users have a role to play and a contribution to make to the safe and secure use of technology and the information/data that it holds. 4. Definition 4.1 Access control rules and procedures are required to regulate who can access Calderdale Council information resources or systems and the associated access privileges.

Compromising of the system and/or other network systems. 5.3 Non-compliance with this policy could have a significant effect on the efficient operation of the Council and may result in financial loss and an inability to provide necessary services to our customers. 6. Applying the Policy 6.1 Choosing Passwords Passwords are the first line of defence for our ICT systems and together with the user ID (LID) help to establish that people are who they claim to be A poorly chosen or misused password is a security risk and may impact upon the confidentiality, integrity or availability of the Council s computers and systems. 6.2 Password Construction Strong passwords MUST have a minimum of seven characters and consist of characters from three of the following groups:- Group Examples Uppercase characters A, B, C...
