Snort Network intrusion Detection System

Snort is a free and open source network intrusion prevention system (NIPS)[citation needed] and network intrusion detection system (NIDS)

Snort's open source network-based intrusion detection system (NIDS) has the ability to perform real-time traffic analysis and packet logging on Internet Protocol (IP) networks. Snort performs protocol analysis, content searching and matching. These basic services have many purposes including application-aware triggered quality of service, to de-prioritize bulk traffic when latency-sensitive applications are in use.

The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, common gateway interface, buffer overflows, server message block probes, and stealth port scans.[10]

Snort can be configured in three main modes: sniffer, packet logger, and network intrusion detection.[11] In sniffer mode, the program will read network packets and display them on the console. In packet logger mode, the program will log packets to the disk. In intrusion detection mode, the program will monitor network traffic and analyze it against a rule set defined by the user. The program will then perform a specific action based on what has been identified.

Open Source Security Solutions and Network Management

 

Network Managent Solutions integrated with Open Source security solutions  make a powerful Solutions for large and small enterprise. Network management solutions like OpenNMS and Nagios provide the basic framework for the Monitoring and  logging Network Events and SNMP traps for the devices connected to network.

Network security and intrusion detection is critical component of business network. Open source intrusion detection software like OPENSEC and Snort provide bulk of the intrusion detection facility.

OSSEC is a free, open-source host-based intrusion detection system (HIDS). It performs log analysis, integrity checking, Windows registry monitoring, rootkit detection, time-based alerting, and active response. It provides intrusion detection for most operating systems, including Linux, OpenBSD, FreeBSD, OS X, Solaris and Windows. OSSEC has a centralized, cross-platform architecture allowing multiple systems to be easily monitored and managed.

 

 OPSEC integrates with your Cloud and Network Infrastructure to provide enterprise security.  We work with OSSEC, Snort, Nagios, OpenNMS and Openstack cloud to provide an integrated solutions. Please contact us for details.

IT Service Management (ITSM)  and Lean, Devops and  Continuous Delivery

 

Definition of Information Technology Service Management

IT service management (ITSM) refers to the entirety of activities – directed by policies, organized and structured in processes and supporting procedures – that are performed by an organization to plan, design, deliver, operate and control information technology (IT) services offered to customers. It is thus concerned with the implementation of IT services that meet customers' needs, and it is performed by the IT service provider through an appropriate mix of people, process and information technology.

 

Differing from more technology-oriented IT management approaches like network management and IT systems management, IT service management is characterized by adopting a process approach towards management, focusing on customer needs and IT services for customers rather than IT systems, and stressing continual improvement.

 

The IT Chaos and Solutions Process

Now a days, the future of a company appears to hang almost entirely on Enterprise e-commerce and mission critical ERP. The political storm brewing behind such  projects, led by  the marketing manager and hidden agenda, adds further tension. Faced with the conflict of E-commerce and ERP requirements against firefighting and competing projects, IT manager  and his team enter a spiral of problems, mistakes, gloom and despair. Thanks to a growing insight into Lean, Agile and DevOps concepts, IT manager  and his team can  gradually evolve their way of working. By the time NextKillerProject  arrives later in the scenario, they’re able to release and support the project reliably, efficiently, and emerge with strengthening morale out the other side. Value of  central change management and Information Technology Service Management (ITSM) is proved and demonstrated to know-all skeptics. No more hardware upgrades causing software firefighting and vice versa.

 

A  Keen Computer Observation

 The problem  addressed by ITSM   has appeared in  almost all the organization that has formal and informal IT department. The problem the ITSM addresses is not only technical like network management or software development- it  encourages a culture of system level thinking and teamwork. The central change management, testing and experimentation, rollout and rollback scenario consideration is crucial for success. 

 

Summary

ITSM stresses the fact that Systems Engineering is necessary for avoiding core IT chaos involving Software, Hardware and IT fire-fighting and finger pointing with individual inner agenda and organizational politics . It’s not the case that, DevOps and Agile approaches to working have magically evaporated all the challenges facing a normal organization. Conflict, incidents and mistakes are inevitable – what counts is how team members grow to manage and resolve them using Systems Engineering principals . In the end the organization must have structure, process, and a more open attitude to change and adaptation to stand them in good stead. An approach to System Level thinking and systems approach is necessary

At its most practical, The ITSM is an illustrative series of process and suggestions for ways to evolve IT from a function that’s viewed as a bottleneck to one that’s widely agreed to be an indispensable capability. And at both levels, The enterprise ERP and E-commerce needs  DevOps that includes the wider organization, and the wider organization can learn a lot from DevOps and ITSM.

Defining the Problem:

  Computerization and digital transformation of workplace is common in Canadian & US workplaces.  This means more and more computers, servers and cloud computing is injected in our dally life. Yet the basic questions remains to be asked, have we paid attention to the issue of maintenance and repair of modern computer infrastructure. The manual mode of IT support is not feasible and is economically constraining to be the least.

 

 As the digital transformation affects every part of business operation, IT maintenance and trouble shooting has remained stuck in the   1990s. Typical IT person can handle 10 computers and server and network, yet organization now has 200-500 PCs, Cloud and Servers. Does this means we must have an IT department of 50 people to handle 500 computers.   A strategic analysis of the maintainability  and scalability of Information Technology is necessary [10].
