Network Security – The Road Ahead

Introduction

Network Security is the next technology that is set to take over the software market. More offshore projects and the transfer of information The wire across the wire has increased the intensity of the desire to secure the network. According to the famous adage the safest computer is one that has been disconnected by the network(making it nearly useless). 

Security of the network
is becoming more of an essential requirement. It is interesting to note that the kind of security

A comprehensive report listing is an essential element to
keep an eye out for. Here’s a list of studies that could prove useful
for any business:

Expectations for reports from devices at the edge, such as firewalls:

  1. Live monitoring
  2. Security reports
  3. Virus reports
  4. Attack reports
  5. Traffic reports
  6. Protocol usage reports
  7. Web usage statistics
  8. Reports on the use of mail
  9. FTP reports on usage
  10. Telnet usage reports
  11. VPN reports
  12. Reports on traffic inbound and outbound
  13. Intranet reports
  14. Internet reports
  15. Trend reports

Expectations from reports on compliance and internal monitoring:
( look up the compliance sub-headings for information on reports regarding compliance)

  1. User Audit reports (successful/unsuccessful login attempts)
  2. Audit policy changes (ex: change in privileges etc)
  3. Changes to passwords
  4. Account Lockout
  5. Changes to user accounts
  6. IIS reports
  7. DHCP reports
  8. MSI reports( lists the products installed/uninstalled)
  9. Group policy modifications to group policy
  10. RPC reports

acts.

HIPAA Compliance:

HIPAA is the definition of Security Standards for monitoring and auditing systems
activity. HIPAA regulations require investigation of all logs,
including OS
and application logs, including and perimeter devices like IDSs,
as well as insider activities. Below are a few crucial reports that
must be in the right place:

  1. Users Logon Report: HIPAA requirements (164.308 (a)(5) Log-in/log-out monitoring) clearly stipulate that user access to the system should be documented and monitored for potential misuse. Keep in mind that the goal is not only to identify hackers, but also to record the use of medical information from legitimate patients. Most of the time the fact that the information is documented is enough to deter malicious activities similar to having a security camera within a parking area.
  2. Logoff report for user Logoff Report: HIPAA requirements clearly state that access to the system should be documented and monitored for potential abuse. Keep in mind that the goal is not only to identify hackers, but also to record the use of medical information from legitimate patients. Most of the time the information that is documented is enough to deter criminal activity, similar to having a security camera within a parking area.
  3. Logon Failure report Security logon report is able to log all failed login attempts. The name of the user, the date and time are recorded in this report.
  4. Audit Logs access report: HIPAA requirements (164.308 (a)(3) Review and audit access logs) requires procedures to review regularly the records of system activities like audit logs.
  5. Security Log Archiving Utility:Periodically, the system administrator will be able to back up encrypted copies of the log data and restart the logs.

SOX Compliance:

The information provided is accurate and factual. Here are a few of the crucial
Reports to be looking for:

  1. User Logon report: SOX requirements (Sec 302 (a)(4)(C) and (D) Log-in/log-out monitoring) clearly stipulate that user access to the system should be documented and monitored for potential misuse. Keep in mind that the purpose of this is not only to identify hackers , but also to record access to medical information from legitimate patients. Most of the time the fact that the information is documented is enough to deter malicious activities similar to having a security camera within a parking area.
  2. Logoff report for user Logoff report: SOX requirements (Sec 302 (a)(4)(C) and (D) clearly stipulate that access to the system should be documented and monitored for abuse. Keep in mind that the purpose of this is not only to identify hackers, but also to record access to medical information from legitimate patients. Most of the time the fact that the information is documented is enough to deter malicious activities similar to having a security camera within a parking area.
  3. Login Failure report The security logon feature is able to log all failed login attempts. The name of the user as well as the date and time are recorded in this report.
  4. Audit Logs access report: SOX regulations (Sec 302 (a)(4)(C) and (D) Review the audit logs of access) requires regular reviews of system activities like audit logs.
  5. Security Log Archiving Utility:Periodically, the system administrator will be able to back up encrypted copies of the log data and restart the logs.
  6. Changes to the management of track accounts: Significant modifications to the internal controls, sec 302 (a)(6). Changes to the security configuration settings , such as the addition or removal of a user account from a group that is admissible. Changes in security configurations can be monitored through the analysis of the logs of events.
  7. Changes to the security audit policy: Internal controls Section 302 (a)(5) by monitoring the logs of events for modifications to Security Audit Policy.
  8. Monitor individual user actions: Internal controls, sec 302 (a)(5) by monitoring user activities.
  9. Access to track applications: Internal controls sec 302 (a)(5) through the tracking application process.
  10. Access to files and directories: Internal control of sec 302 (a)(5) for any violation of access.

GLBA Compliance:

The Financial Services Modernization Act (FMA99) was enacted in
January 1999 (PL 106-102). Also known as the
The Gramm-Leach Blair Act also known as GLBA, Title V of the Act regulates the steps

  1. User Logon report: GLBA compliance guidelines clearly stipulate that user access to the system should be documented and monitored for potential misuse. Keep in mind that the goal is not only to identify hackers , but also to record the use of medical information from legitimate patients. Most of the time the fact that the information is documented is enough to deter malicious activities similar to having a security camera within a parking area.
  2. Logoff report for user Logoff report: GLBA regulations clearly stipulate that access to the system should be documented and monitored for abuse. Keep in mind that the goal is not only to identify hackers, but also to record access to medical information from legitimate patients. Most of the time the fact that access is documented is enough to deter malicious activities similar to having a security camera within a parking area.
  3. Logon Failure report: The security logon feature logs every unsuccessful attempt to login. The name of the user as well as the date and time are recorded in this report.
  4. Audit Logs access report: GLAB specifications (review as well as audit logs of access) requires procedures to review regularly the records of system activities like audit logs.
  5. Security Log Archiving Utility:Periodically, the system administrator will be able to back up encrypted copies of the log data and restart the logs.

Conclusion

“Network Security” has to be carried out both internally and externally.
Externally, solving the issue is a massive task
which needs expertise and mostly help from softwares such as EventLog Analyzers(compliance and internal monitoring of internal machines) and Firewall Analyzer(virus,attacks
and monitoring the traffic of edge devices for traffic monitoring).
