SECURITY
AUDIT
A security audit is a systematic evaluation of the security of a
company's information system by measuring how well it conforms to a
set of established criteria.
A thorough audit typically assesses the security of the system's
physical configuration and environment, software, information
handling processes, and user practices. Security audits are often
used to determine regulatory compliance that specifies how
organizations must deal with information.
At its root, an IT security audit includes two different
assessments. The manual assessment occurs when an internal or
external IT security auditor interviews employees, reviews access
controls, analyzes physical access to hardware and performs
vulnerability scans. These reviews should occur, at a minimum,
annually. Some organizations, however, prefer to do them more
frequently.
Goal of Security Audits
- Keep sensitive data protected
- Keep compliance programs up to date (i.e. HIPAA)
- Identify security loopholes & ensure the level of security
required for the type of data
- Ensure that staff are correctly following security
protocols
- Implement proper cybersecurity awareness education and
training
- Establish precautionary measures & procedures
- Give peace of mind to management, staff, and customers
- Make more effective security decisions based on data analysis
from the audit
- Use findings from audit to create and implement new security
policies and procedures
- Identify potential risks and threats that are most likely to
affect your organization
- Identify and prioritize risk responses
- Better prepare the organization to protect against potential
threats
- Uncovering hidden risks
- Prevent security breaches and reduce the impact of
breaches

software
- Reduce security problems that result from human error
- Keep technology up-to-date
- Protect against incorrect or unwanted changes
Importance of establishing best practices within and
organization
- Security audits are important because they help you identify
your biggest security risks or flaws in your system so you can make
changes that will protect your organization from those risks.
- Starting with a security risk assessment allows corporate
management and IT staff to work together. Management needs to make
decisions that mitigate risk while IT staff implements them.
Working together under the same risk assessment gives everyone the
information they need to protect the organization.
- Regular audits can also help improve the effectiveness of your
auditor as they learn more about your organization and its
technology, processes, issues, and needs.
- Risk assessments provide accessible report focused on a “need
to know” basis so that all involved can take the appropriate level
of responsibility.
- An Organizational security risk assessment educates internal
stakeholders so they can see the value of mitigating the critical
risks and approve additional financial support.
