Finjan Simple Network Management Protocols (SNMP)

Network administrators and Information Security Officers (ISOs) have a tough job monitoring and marshaling the resources of corporate infrastructure – especially at a time when enterprises are expanding their operations beyond localized data centers and campuses to dispersed networks having the potential to span the globe. Fortunately, there’s a standardized set of mechanisms that can streamline and rationalize network management … Read More

The Non-Interference Model

Finjan The Non Interference Model

Security models of control are used as a way of formalizing a security policy. They determine in one way or another how security will be implemented across a system or network, which subjects are permitted access to the system, and which objects they are allowed access to. These security models are typically put in place by enforcing confidentiality, integrity, or … Read More

Finjan Trusted Computing Base or TCB

As well as an infrastructure of components and processes, a computer system also requires a security architecture defining its capacity to resist attacks and attempts at infiltration and providing its capability to detect and respond to threats and changing conditions. With susceptibility to attack being as critical a factor to system stability as the potential failure of its component parts, … Read More

Finjan Common Criteria for Information Technology Security Evaluation

The need to ensure that consumers have access to IT products which are inherently secure has raised a demand for some kind of internationally recognized standard for evaluating and certifying equipment and software. Such a standard exists in what’s collectively known as the Common Criteria or CC. Common Criteria or CC More formally known as the “Common Criteria for Information … Read More

Finjan Network Security Objectives and Attack Modes

A network exists when two or more computing systems are linked in a mutually dependent relationship that enables them to share resources and/or information. The connection between systems may be a physical one – as is the case with a traditional private data center, where banks of servers and systems are connected by cables, routers, and switches. It may also … Read More

Finjan Border Gateway Protocol

With the increasing integration of cloud-based telecommunications and data transmission over the internet, there’s a need for different corporate and private networks to interact with each other. To preserve data integrity and to ease the flow of information, it’s essential to have standardized pathways and rules to govern this interchange. One of these is the Border Gateway Protocol or BGP. … Read More

Finjan Biba Integrity Model

Confidentiality, integrity, and availability make up the “security triad” as it applies to data. And one of the principal security models dedicated to preserving the integrity of information is the Biba integrity model, which we’ll be looking at today. Biba Integrity Model – Some History For years, matters of data confidentiality were largely dealt with by the Bell-LaPadula model, which … Read More

Finjan TCP/IP Vulnerabilities

Part of the beauty of using the internet to move information around lies in the apparently seamless and user-friendly way in which transmissions are accomplished. This stems in large part from the use of a common set of transmission/reception mechanisms or protocols – but it’s the very standardization of these methods that leaves them so open to exploitation and attack. … Read More

Finjan Egress Monitoring

With so many threats looming from intruders and malicious software originating outside of systems and corporate LANs, it’s easy to overlook the fact that security lapses and vulnerabilities can equally emanate from within a connected system or private network, and make their way out to cause damage as well. So for comprehensive security coverage, it’s essential not only to have … Read More

Network DMZ Zones

Finjan Network DMZ Zones

Online transactions are an unavoidable part of today’s economy. But when corporate networks expose their infrastructure and resources to the largely unsecured public internet, they throw themselves open to the possibility of attack. One way of reducing this risk is through the establishment of safe zones known as DMZ. What’s a DMZ? DMZ stands for demilitarized zone – a throwback … Read More
