3. IT asset classification and control
One of the most laborious, but essential tasks is to manage inventory
of all the IT assets. These include: information assets (databases),
software assets (applications), and physical assets (servers, PDA's,
etc). These IT assets need to be classified to indicate the desired
degree of protection. The classification should result in appropriate
information labeling to indicate whether it is sensitive or critical
and what procedure is appropriate for copy, store, transmit or destruction
of the IT asset.
4. Personnel Security
Human errors, negligence and greed are responsible for most thefts,
frauds or misuse of IT assets. Various proactive measures that should
be taken include:
- Development of personnel screening policies,
- Getting signed confidentiality agreements from all employees,
- Establishing terms and conditions of employment and
- Implementing information security education and training.
Alert and well-trained employees who are aware of what to look
for can prevent future security breaches.
5. Physical and Environmental Security
Designing a secure physical environment to prevent unauthorized
access, damage and interference to business premises and information
is usually the beginning point of any security plan. This involves
establishing a physical security perimeter which includes: physical
entry & access controls; creating secure offices, rooms, and
facilities; providing protection devices to minimize risks ranging
from fire to electromagnetic radiation; providing adequate protection
to power supplies and data cables. Cost effective design and constant
monitoring are two key aspects towards maintaining adequate physical
security control.
6. Communications and Operations Management
Properly documented procedures for the management and operation
of all information processing facilities should be established.
This includes detailed operating instructions and incident response
procedures.
Network management requires a range of controls to achieve and
maintain security in computer networks. This also includes establishing
procedures for managing remote equipment including equipment in
user areas (or at homes of employees who telecommute). Special controls
should be established to safeguard the confidentiality and integrity
of data passing over public networks. Special controls may also
be required to maintain the availability of the network services.
Exchange of information and software between external organizations
should be controlled and should be compliant with any relevant legislation.
There should be proper information and software exchange agreements,
the media in transit needs to be secure and should not be vulnerable
to unauthorized access, misuse or corruption. The HIPAA Security
rule positions this as an addressable requirement, where the Covered
Entity is responsible for determining what is the most reasonable
way to implement this protection (if at all).
Electronic commerce involves electronic data interchange, electronic
mail and online transactions across public networks such as Internet.
Electronic commerce is vulnerable to a number of network threats
that may result in fraudulent activity, contract dispute and disclosure
or modification of information. Controls should be applied to protect
electronic commerce from such threats.
