but can be bypassed with physical access to an open computer and should not be used for sensitive information. The other method of securing files is by encrypting the information in the files using an Encrypting File System (EFS)‚ which employs public key encryption privileges (Strengthen Your Users ’ File Security‚ 2003). A firewall prevents access to an internal system from the outside the company via the internet on any open ports. A firewall will also prevent internal network users from accessing

network will be secured in each area. The first step to the network hardening plan resides in how you will build the network and then from there how you will secure each section of the network. This paper will discuss access control measures‚ encryption‚ PKI‚ certificates‚ OS hardening‚ application hardening‚ transmission‚ remote access protection protocols‚ wireless security‚ anti-virus software as well as spyware‚ and email security. One of the first steps in securing a network is setting the access

VPN software enables private information to be shared over the public network while being encrypted. Aircraft Solutions has many groups and users that need different levels of access to the internal network. Clients need access to the company website‚ employees need to be granted different levels of access to certain

Certificate Authority or Certification Authority (CA) is an entity‚ which is core to many PKI (Public Key Infrastructure) schemes‚ whose purpose is to issue digital certificates to use by other parties. It implies a trusted third party. 3. An attacker can create a certificate for any domain. This certificate will appear to be signed by a trusted CA. Thus‚ you will see

The use of digital certificates and the public key infrastructure (PKI) has emerged as the de facto standard for conducting secure transaction over the public internet. It has become increasing clear that the security infrastructure on which most of e-commerce is based is actually quite fragile. This paper will focus on the framework surrounding the usage of digital certificates and

Introduction : We have seen a spate of cyber frauds in the recent past. The frequency and scale of the incidents has created a lot of concerns for the banks‚ regulators and customers. What do banks in India have to learn from these? Are they doing enough to ensure that we don’t end up as sitting ducks? What preventive measures to take to face this new menace? Before we consider these and other related questions‚ we need to understand the anatomy of cyber frauds. Cyber Fraud is a generic term used

There are many different ways to go about this topic the one I am going to pick is a public key infrastructure (PKI). One of the security options that we are going to use is Privacy or confidentiality. This will keep all information secret from all people unless you are authorized to see it. This will help with employee’s not finding things that

We propose a cryptographic scheme that has to be executed in order to achieve the desired security levels at every exam stage. Keys words: e-learning security‚ electronic exams (eexam)‚ cryptographic protocols. 1 Introduction In e-learning environments‚ students and teachers use Internet on a regular basis in order to follow/receive lectures‚ ask/answer questions and send/receive
