Security Best Practices
n Evaluate
Risks: Assess internal and external business and security environments.
Analyze all the available historical data to look for patterns and identify
vulnerabilities. What are the special features of your business? What is your
network architecture like? Is your current network security infrastructure
adequate? How critical is the role played by the network in your business?
n Come up with
a Security Policy: Based on risk evaluation, design and implement a security
policy, and link that policy to business risks. Involve business managers in
risk assessment: Involving business managers in identifying potential threats,
vulnerabilities and consequent impact on business operations could help them
better understand the imperatives of network security.
n Establish a
Central Management Focal Point: Designate a central group to carry out the
key activities. Provide the central group with ready and independent access to
senior management. Designate dedicated funding and staff. Enhance staff
professionalism and technical skills.
n Promote
Awareness: Continually educate users and others on risks and other related
policies, use attention-gaining and user-friendly techniques.
n Monitor and
Evaluate Policy and Control Effectiveness: Monitor factors that affect risk
and indicate security effectiveness. Use results to direct future efforts and
hold managers accountable. Stay alert to new monitoring tools and techniques.
n Distinguish
between policy and Guidelines: While the security policy should outline the
fundamental outline that the senior management considers imperative, guidelines
should provide more detailed rules for implementing broader policies. Guidelines
can also be designed as an educational tool that can help network users
understand and follow the desired security practices.
n Incident-handling
Mechanism for Security Breaches: A security systems investigation procedure
that addresses evidence preservation and forensic examination must be formulated
with a trained response team in place, so as to tackle emergency.
n Third-party
Assessment: External third-party audits should be regularly carried out to
get an independent assessment of network security effectiveness. Look for these
in one-in-all box: If you are looking for a complete security appliance then it
must have at least firewall, anti-virus, IDS and content-inspection functions.
However, look if too many features in one box are affecting its ability to
perform. In many cases, that is likely. So avoid asking for everything in one
box if your security requirements are complex.
n See that the
Box Goes with the Security Policy: This is the first important factor that
any enterprise should look for before buying any security appliance. One should
not buy a box just because it can perform umpteen security functions. Check if
the box is capable enough of meeting the stated objectives of the security
policy. Also, security appliance is deployed in an extremely dynamic environment
and requires constant evaluation to manage the threats posed. So check the box
for scalability.
n Have a Patch
Management System in Place: Such a system is needed to protect networks from
virus and worm attacks. Many attacks in past have happened because an enterprise
didn’t go for a patch update in time.
n Step-by-step
Buying: Organizations can have a diverse range of security needs ranging
from anti-virus protection to malicious content inspection and hacker attacks.
However, an organization may not need all the security features at one go.
Depending on the context, buy only what you need today, but keep the option of
upgrading always open.
