Information Security professionals must employ techniques which can prevent any threat from exploiting any vulnerability as much as possible. Threats could target privacy, reputation and intellectual property along with lots of other data.

Data Classification

In order for the policy to be entirely effective and be able to know which data protect the data must be classified into 3 categories

  1. Category 1 – Data that can be freely distributed to the public.
  2. Category 2- Internal data only not meant for outsiders.
  3. Category 3- Sensitive internal only data that could affect operations if disclosed to public.
  4. Category 4- Highly sensitive internal data that could put an organization at financial or legal risk if disclosed to public.

Security Prevention Measures

Security prevention measures ensure security and prove comfort for the business and also the customers. Prevention measure could consist of many things.

  1. Existing Security Measures.
  • Access control which ensure only allowed users granted permission to access the database may do so. This applies to accessing, modifying and viewing the data.
  • Frequent SQL input validation tests are conducted in order to ensure no unauthorized users can access the database.
  • Three separate cloud based servers are available, two of which are for back up purposes this ensures the availability of the data in the case of the intrusion on one of the servers.
  • All servers are backed up daily.
  • Database auditing is frequently conducted.
  • Database log files are frequently checked to observe in case of any malicious activity.
  • All database security is managed by a third party in order to ensure maximum security.
  • In order to avoid Denial of Service (DOS) attacks which could affect the availability the web applications are put on different servers.
  • Role-Based Control is used in order to make sure employees can only retrieve content from the database that they are authenticated and authorized to.
  • Discretionary access control is only permitted to the database department as no other faculty or staff needs access or is permitted to access.
  1. Flaws which need reviewed
  • Password policy is not implemented strictly to students which can result in the compromising of an account.
  • Solution: Password Policy MUST be applicable to all therefore, database department must make it mandatory.
  • No “honeypotting” is available.
  • Solution: The necessary equipment and software should be purchased for this to be done. This will help the College avoid attacks in the case of SQL injection or any other database attack.
  • No digital certificates are utilised when messages are sent across the website.
  • Solution: Create system to have to send digital certificate/signature to ensure a better level of security.
  • No certified security professionals are currently employed.
  • Solution: Raise issue to Human Resources as a matter of concern and seek the hiring of a professional or train existing staff.
  • Lack of awareness among staff and faculty regarding security in general.
  • Solution: Conduct training for faculty and stuff on how to spot basic threat and potential intrusions etc.

*After these flaws are fixed, policy MUST be reviewed and updated.

  • In the case of an incident CISO must be informed to take necessary action. Any employee failing to do so shall face disciplinary action.
  • Database MUST use views rather than tables no ensure security, all entries must be predefined queries.
  • Database remote access and other distance access must not be enabled by blocking ports such as the telnet port, FTP and others.
