Advanced Threat Defense

Fifteen plus years of efforts to curb IT security issues are still searching for answers. Hackers are getting innovative day by day always having a slight edge over their IT targets. Along came security solutions such as Anti-Malware, Firewalls, IDS, IPS and WAF. Unfortunately there is a common fallacy among all these solutions in the form of vectors, rules that protect either endpoints or perimeter. Fact of the matter is that these solutions offer siloed approach to security. Take a look at this article from Tech Target – search for answers to ‘advanced threat’ defense.

 

The headline caught my attention –

Visibility into what is happening on your network may matter more than stopping an attack. Can technology keep up with advanced threats?

This is a well said statement. There is a reason security issues are termed as ‘virus’. Advanced-Threat-Defense based on behavioral analytics is like a standby doctor constantly diagnosing human body. Behavioral Analytics also unravel the issues that conveniently break deployed security solutions.

NFV, Cloud IMS – Assurance Strategy

As your network architecture evolves and migrates into a public or/and private cloud environment, voice network requires more TLC. Unlike other IP applications, VoIP/IMS applications require consistent timing for flaw-less operation. With the uncertain compute characteristics that cloud brings-in, your vIMS service assurance becomes a priority.

CHALLENGE
Adoption of cloud based call control services is very cost effective. However services like Cloud IMS, lead to service quality and reliability issues as a result of the following:
  • Cloud resource sharing
  • Unpredictable bandwidth availability
  • Coexistence of applications
IMPACT 
vIMS is seen as the first level of Virtualized Network Function (VNF). Failure to deploy vIMS correctly poses a risk to NFV adoption, effecting future marketing and sales initiatives.
DESIRED SOLUTION
DataTap’s capture & aggregation capabilities in all major cloud providers help you with faster resolution times during deployment or service initiation. Continuous monitoring of network, log and event information provides valuable insights and robust service assurance:
  • Cloud and On-Prem support
  • VoIP Quality analysis
  • Application Detection & Correlation

Troubleshoot Call Quality Issues in IMS / VoIP

If you are troubleshooting call quality issues, you must agree that the time is of essence. You need tools that give you more than a bar graph or a pie chart. You need a solution that tells you a story. A story that lays out the critical data points collected from multiple sources over a period of time, defining the context for you.

CHALLENGE
Dropped calls, choppy calls, loss of dial tone and voice delay are the typical problems your customers experience as a result of your network issues. Following are some typical contributing factors:
  • Jitter, Packet Loss and Latency
  • Network misconfigurations
  • Issues with Interconnection provider network
IMPACT 
Consistent poor voice quality increases customer churn rate directly impacting the revenues and service reputation. Voice quality issues increase support call volumes forcing service providers to realign resources from other productive tasks.
DESIRED SOLUTION
Granular visibility to critical voice traffic attributes in realtime helps in effective root cause analysis (RCA). Proactive monitoring and troubleshooting of issues reduce the impact of poor voice quality. You need a voice quality measurement solution that includes:
  • Real-time measurement of Media KPIs, such as RTP Jitter, Packet loss
  • Correlation of Voice traffic attributes with other network attributes
  • SIP/RTP Timing Analysis on origination & termination networks
