Information Security

THE BIG THING in the IT world! Many organizations strive round the clock to secure their information, on premises or in transit or possibly anywhere else. This domain is an ever growing one, where the efforts put in, need to be focused in the right direction otherwise a single misdirection can become a Security Nightmare for your valuable information.

We have simplified this for you by broadly classifying into a Solutions based approach and Services based approach keeping in mind the Confidentiality, Integrity, Availability (CIA) triad

Security Information Event Management (SIEM)

Security information and event management (SIEM) is an approach to security management that seeks to provide a holistic view of an organization’s information technology (IT) security. SIEM combines SIM (security information management) and SEM (security event management) functions into one security management system.

T environments are growing ever more distributed, complex and difficult to manage, making the role of security information and event management (SIEM) technology more important than ever. Here's why:-

Compliance: Almost every business is bound by some sort of regulation, such as PCI-DSS, HIPAA and Sarbanes-Oxley (SOX). Attaining and maintaining compliance with these regulations is a daunting task. SIEM technologies can address compliance requirements both directly and indirectly.

Operations support: The size and complexity of today's enterprises is growing exponentially, along with the number of IT personnel to support them. Operations are often split among different groups such as the Network Operations Centre (NOC), the Security Operations Centre (SOC), the server team, desktop team, etc., each with their own tools to monitor and respond to events. This makes information sharing and collaboration difficult when problems occur. A SIEM can pull data from disparate systems into a single pane of glass, allowing for efficient cross-team collaboration in extremely large enterprises.

Zero-day threat detection: New attack vectors and vulnerabilities are discovered every day. Firewalls, IDS/IPS and AV solutions all look for malicious activity at various points within the IT infrastructure, from the perimeter to endpoints. However, many of these solutions are not equipped to detect zero-day attacks. A SIEM can detect activity associated with an attack rather than the attack itself. For instance, a well-crafted spear-phishing attack using a zero-day exploit has a high likelihood of making it through spam filters, firewalls and antivirus software, and being opened by a target user.

Advanced persistent threats:An APT is generally defined as a sophisticated attack that targets a specific piece of data or infrastructure, using a combination of attack vectors and methods, simple or advanced, to elude detection. In response, many organizations have implemented a defense in depth strategy around their critical assets using firewalls and IDS/IPS at the perimeter, two-factor authentication, internal firewalls, network segmentation, HIDS, AV, etc.

Forensics: A forensics investigation can be a long, drawn-out process. Not only must a forensics analyst interpret log data to determine what actually happened, the analyst must preserve the data in a way that makes it admissible in a court of law. By storing and protecting historical logs, and providing tools to quickly navigate and correlate the data, SIEM technologies allow for rapid, thorough and court-admissible forensics investigations.
