Network Operations & Security Management Proactive Application Monitoring Bandwidth Management

Data Center Server Management

Multi-Functional Management Platform

Integrated Security and Network Management Platform

SIEM, Network Monitoring and Log Management Solution

Real-time availability management across thousands of devices, including applications as diverse as satellite,

cryptography and security devices.

Granular control over any type of event definition, with the ability to collect, normalizes and integrates data from any

device, application or service.

2. All-in-One IT Monitoring

Suresec is a monitoring application to integrate security (SIEM), performance, and availability monitoring in a single

application. We monitor devices, users and applications across the entire IT infrastructure - on premise, in the cloud,

or a hybrid of both - from a single pane of glass.

3. SIEM

Suresec is a web based, agent-less, SIEM, log analysis, network monitoring and reporting software. The software

application monitors, collects, analyzes, and archives logs and monitoring parameters from enterprise-wide network

perimeter security devices, Routers, Switches, SNMP Devices, VM, DHCP servers, Linux or Windows Systems then

generate reports. The devices are, Firewalls, Proxy servers, Intrusion Detection System (IDS)/Intrusion Prevention

System (IPS), and Virtual Private Networks (VPN), Mail Servers like MS Exchange Servers, Zimbra Mail Servers, Postfix

Mail Servers etc.. , distributed Windows hosts, distributed Unix hosts, Routers, Switches, and other SysLog devices,

Application like IIS web server, IIS FTP server, MS SQL server, Oracle database server, DHCP Windows and Linux

servers. The Suresec application generates graphs and reports that help in analyzing system problems with minimal

impact on network performance. Two prominent features of the application are network monitoring and security

reports.

Correlation Engine

The Correlation Engine leverages predefined rules to identify attack patterns and malicious behavior. When trying to

penetrate a system, attackers often take advantage of the fact that security controls are rarely working together and

are rarely monitored. Correlation Engine helps to automate that analysis so that attacks can be quickly identified and

breaches can be quickly contained.

Sample Correlation Rules

User Authentication

Alert on 5 or more failed logins in 1 minute on a single user ID

Attacks on the Network

Alert on 15 or more Firewall Drop/Reject/Deny Events from a single IP Address in one minute

Alert on 3 or more IPS Alerts from a single IP Address in five minutes.

Virus Detection/Removal

Alert when a single host sees an identifiable piece of malware

Alert when a single host fails to clean malware within 1 hour of detection.

Alert when a single host connects to 50 or more unique targets in 1 minute

Alert when 5 or more hosts on the same subnet trigger the same Malware Signature (AV or IPS)

within a 1 hour interval.

Web Server

Files with executable extensions (cgi, asp, aspx, jar, php, exe, com, cmd, sh, bat), are posted to a

web server, from an external source

Black-listed applications

Comprehensive Log Data Collection and Log Management

Being able to collect log data from across an enterprise regardless of their source, present the logs in a

uniform and consistent manner and manage the state, location and efficient access to those logs is an

essential element to any comprehensive Log Management and Log Analysis solution. The Suresec solution

was designed to address core log management needs including:

The ability to collect any type of log data regardless of source

The ability to collect log data with or without installing an agent on the log source device, system or

application.

The ability to "normalize" any type of log data for more effective reporting and analysis

The ability to "scale-down" for small deployments and "scale-up" for extremely large environments

An open architecture allowing direct and secure access to log data via third-party analysis and

reporting tools

A role based security model providing user accountability and access control

Automated archiving for secure long term retention

Wizard-based retrieval of any archived logs in seconds

Cross-platform Log Collection

Today's IT operations require many technologies; routers, firewalls, switches, file servers, and applications

to name a few. Suresec has been designed to collect from them all through intelligent use of agent-less and

agent-based techniques.

Windows Event Logs: Agent-less or Agent-based

Suresec can collect all types of Windows Event Logs with or without the use of an agent. Many Windows-

based applications write their logs to the Application Event Log or a custom Event Log.

Examples of supported log sources that can be collected by Suresec in real time include:

Windows System Event Log

Windows Security Event Log

Windows Application Event Log

Microsoft Exchange Server application logs

Microsoft SQL Server application logs

Windows based ERP and CRM systems application logs

Syslog

Many log sources, including most network devices (e.g. routers, switches, firewalls) transmit logs via

Syslog. Suresec includes an integrated Syslog server for receiving and processing these messages. Simply

point any syslog generating device to Suresec and it will automatically begin collecting and processing those

logs.

Flat File Logs

Suresec can collect logs written to any ASCII-based text file. Whether it is a commercial system or

homegrown application, Suresec can collect and manage them.

Examples of supported log sources using this method include:

Web servers logs (e.g. Apache, IIS)

Linux system logs

Windows ISA server logs

DNS and DHCP server logs

Host based intrusion detection/prevention systems

Homegrown application logs

Exchange message tracking logs

Universal Database Log Collection and Log Management

Since so much sensitive information resides in databases, it is important to monitor and track access and

activity surrounding important databases. The actual and reputational cost of a theft of customer records can

be very large. Suresec can help. Suresec collects, analyzes, alerts, and reports on logs from Oracle,

Microsoft SQL Server. It also captures data from custom audit logs and applications that run on the

database. This capability enables customer to use Suresec for real-time database monitoring to guard against

insider and outsider threats.

Scalable Log Centralization

Suresec is architected to scale easily and incrementally as your needs grow. Whether you need to collect 10

million or more than 1 billion logs per day, Suresec can handle it. With Suresec you simply deploy the

capacity you need when you need it, preserving your initial investment along the way. Deployments can

start with a single, turnkey appliance and grow easily by adding incremental log manager appliances as

needs expand. With Suresec’s “building blocks” distributed architecture, you can access and analyze logs

throughout your deployment with ease.

Log Archiving and Retrieval

Many businesses have compliance requirements to preserve historic log data and be able to provide it in its

original form for legal or investigative purposes. Collecting, maintaining and recovering historic log data

can be expensive and difficult. Imagine trying to recover logs from a specific server two years ago. Were

the logs archived or saved anywhere. If so, where have the logs been stored? What format are they in?

Can the correct archived log files be identified among the tens of thousands (or millions) of other archive

files…in a reasonable period of time? With Suresec, the answers to these questions are easy.

Activity Auditing

For compliance verification, users’ and administrators’ actions within Suresec are logged. Suresec user

activity reports provide powerful proof that Suresec is actively used to analyze log data for compliance

purposes.

5. Performance & Availability Monitoring Features

Suresec network monitoring capability besides security management is unique feature of Suresec platform.

Suresec Performance and Availability Management gives you an integrated view into the health of your

network, systems, applications and virtualization environments. We monitor performance and availability

metrics, application health, infrastructure resource usage, track and correlate network and application

behavior, baseline metrics and detect anomalous activity.

Types of Monitors:

Based on the parameters they measure, we have categorized Suresec monitors broadly into four types. They

are:

Operating Systems: Microsoft® Windows Server™,2000/2003/2008/2012,Microsoft Windows®,

XP, Vista, 7, 8,RedHat® Linux, SuSE® Linux, IBM AIX®, Hewlett-Packard HP-UX®,

SunSolaris™, VMware®.

Application Monitors : WebLogic, IBM WebSphere, Microsoft Exchange, Microsoft IIS, Microsoft

SQL Server, MySQL, Oracle, Tomcat, FTP, HTTP, URL, Port.

Network Monitors: Cisco® & Other Network Devices, DHCP, SNMP Devices, SNMP Trap, HP,

Avaya, Dell.

Advanced Monitors : Virtual Machine, Novell, Vsphere

Infrastructure: Active Directory, Dell OpenManage™,HP Systems Insight Manager ,(HP SIM) ,IBM

Director ,Protocol Availability, Syslog, Windows Event Log

Cross-domain Visibility

Our cross-domain monitoring approach spans server, storage, network, virtualization and applications to

automatically cross-correlate metrics in real-time, freeing you from the task of gathering this information

from multiple sources.

Business Service Management

We monitor the performance health of your business services in addition to individual devices and

applications.

Root-cause Analysis

We automatically connect the dots, in real-time, to rapidly isolate the root cause of security and network

issues. This is valuable in virtualized environments where problem root causes vary with time due to

vMotion and other changes.

SLA Monitoring & Powerful Reporting

Service level trends and tracking is now on your fingertips. A powerful tool to manage predict and prevent

problems before they affect to users and business.

SLA Dashboard & Business Views

Get full visibility into your organization through real - time SLA monitoring and Business Views.

Trend Monitoring&Capacity Planning

You can use system statistics to monitor the bandwidth of all the volumes, interfaces, and CPUs,Disks that

are being used on your system.

You can also monitor the overall CPU utilization for the system. These statistics summarize the overall

performance health of the system and can be used to monitor trends in bandwidth and CPU utilization.

You can monitor changes to stable values or differences between related statistics. These differences then

can be further used for capacity planning

Fault Management

Suresec Fault Management unique capability is the set of functions that detect, isolate, and correct malfunctions in

your network. When a fault or event occurs, a network component will often send a notification to the network

operator. An alarm is a persistent indication of a fault that clears only when the triggering condition has been

resolved.

6. SURESEC ADVANTAGES
