...attack are HTTP, used for connecting to web pages, DNS, used for turning a web address to an IP address, and SMTP, used for email transfer (The Growing Threat, 2012). Since they use well known and frequently used protocols to exploit, these attacks easily bypass normal traffic inspectors. The protocols for web must be open on the firewall and IDS because if they weren’t, normal web traffic would not go through. This would make the internet useless for everyone. In order to mitigate this issue and still have connectivity, there are two things the University can do. First, the IT staff can deploy a Host-based Intrusion Prevention System (HIPS). This will be deployed to all of the University computers and centrally managed by a server in the data center. It is able to look at traffic and use behavioral analysis to prevent attacks. It will flag traffic or system functions that are not normal. It builds a baseline by looking at normal traffic patterns and use. If the computer starts to stray from this, it will alert the administrator (Chee, 2008). The benefits of installing a HIPS are large. This will protect the computers running on the...

...Increasing Security in Bank Network Security to Prevent Information Leaks There are three main pillars of bank network security including firewalls, intrusion detection and intrusion prevention. Additional network security and added firewall protection will help banks keep information safe and confidential. An overkill of security, having mass protection from viruses, and doubling up on firewalls will aid in this effort. Taking measures to extremes to ensure the best protection from any type of malware or virus threat, and keeping information secure where it’s meant to be is a huge concern of banks. Ensuring the protection of client’s information assists with the bank staying in business and keep customers coming. Clients need the knowledge that their information and money is protected and not accessible to any outside intrusion. If a client is aware of the extreme measures of protection taken on their delicate information, they will feel more comfortable in using a banking system. A well protected bank network, with top of the line security monitoring is a much safer pick to cliental, and network security in banking is just as important as general security over the bank! An alarm system, cameras, and locking the building and safes holding moneys, pose the same type of protection of individual moneys in being transferred in some way. Network security is slightly more demanding than general security however, because an intruder in a bank’s network has access to...

...19 Conclusions 20 Page 2 of 20 SUMMARY An overview of the data for all three networks shows that each network was compromised in one manner or another. For instance, network #1 had intrusive access via a Microsoft ISS web server to cmd.exe, which allowed complete access to the system. This was achieved through a buffer overflow attack against IIS. As such, the administrator of this network should ensure that all systems are fully patched in order to avoid known exploits. For network #2, an exploit via phpBB enabled access to the system. Network #3, “EXPLOI~1.RTF”, which a user must have downloaded, was executed, opening up a backdoor into the system. Unfortunately, as outlined in my conclusion, an in-depth analysis of this data was aborted partly due to time mismanagement and a very large course load for the term. INTRODUCTION This assignment consisted of the analysis of three different networks with their own associated log files and packet dumps. In total, the data to be analyzed consisted of 3.7 GB. In order to analyze this very large amount of data, a variety of different tools were employed. • Snort – A free and open source network intrusion prevention system. Snort was used to replay all of the provided packet captures against the latest rule-sets...

...An Intrusion Detection System (IDS) is used to monitor all network activity and identify any unusual activity that attack and attempt to break into the system. The main function of IDS is to warn about any suspicious activity. An ID reviews the network traffic and data and warns about any attack with displaying an alert. The IDS looks for any virus, worms and hackers with the help of intrusion signatures or attack signatures. IDS can provide notifications of only known attacks. An Intrusion Prevention System (IPS) is the net level of security which provides security to all types of system levels. It provides the security rules with IDS to alert systems. It allows the administrator to provide action upon alert. An ID informs of a potential attack and IPS makes attempts to stop it. IPS has the capability to prevent known intrusion signatures and also some unknown attacks because of its database with generic attack behaviors. IPS is generally considered to be the "next generation" of IDS. An IDS is a reactive security mechanism and an IPS is a proactive security mechanism. IDS system recognizes that an attack is occurring and an IPS determines whether incoming traffic is 'probably' malicious before it is received. IDS can reject any attack or access to passwords, id’s, etc. IPS can categorize traffic and determine whether it’s malicious or not. IDS and IPS are designed for different purposes, but their technologies are similar. IDS is best used to explain about what happened in...

...Security Solutions Jonathan E. La Rosa July 22, 2014 NTC/411 Randal C. Shirley Security Solutions Firewalls have been around for years. In that time, they have protected various different organizations and corporations from possible hacker attacks. They play a critical part in protecting the internal network and making sure that packets are screened and checked before being provided access. Although firewalls are extremely powerful, especially in today’s world, they cannot be the only source of protection that the network can have. Various other technologies need to be used in order to actually make sure that the data is secure and that information has not be tampered with. Intrusion Prevention Systems, or IPS’, as well as Intrusion Detection Systems, or IDS’ are great in making sure that the network is free of any attacker or unwanted individual. These different technologies working together can provide the best protection possible, although they do have to be monitored in order to make sure they are working in the best way possible. Firewall Protection Managing firewalls is a fundamental function in making sure a network is secure. Network security managers are the main individuals who have to make sure that the firewall is constantly working in the most effective and efficient way possible.

...determined that the Myrtle Group has security challenges that are uniquely different from that of the Bellview Law group. Myrtle & Associates has a more modern IT infrastructure. Their Case Management System is Web based therefore presenting an additional set of security challenges. In addition, there Domain Controllers and there File Server operated on Windows Server 2008 while the Bellview systems utilize Novell. The Bellview Law Group has a legacy Case Management System. Their network at this point can only be accessed at the onsite location. The Bellview Company has no web or wireless system access and all of its system assets are hard wired locally. These systems currently utilize Legacy Novell backbone to support its File Servers, Case Management System and it’s Directory Services. While connecting the two networks can be accomplished, there are some potential challenges facing the MAB network. A Windows Server 2008 Domain controller should be added to the Bellview side of the network. The MAB leadership must consider obtaining some immediate cross-training so that associates can obtain the knowledge to operate both case Management Systems. Future phase of this project will require upgrading from legacy Case Management Systems to a universal Case Management System to be used by all authorized MAB employees.

...security, it is important for our network and its resources to be kept secure from possible intrusion from outside sources. Installing of an IDS policy is an important thing in keeping the network safe. Installing a Network IDS (NIDS) onto a network requires a significant amount of thought and planning. In addition to the technical issues and product selection there are resource issues, from product cost to manning the sensor feeds and supporting the infrastructure that must also be considered. When installing an IDS a policy needs to be developed to ensure responsibilities are clearly defined. This is especially important when delivering an IDS capability remotely or to another organization's network. On the subject of failing hardware, people administering the target network must be made fully aware that if network taps are used, even fail safe taps can take up to a second for the interfaces to re-negotiate and could potentially disrupt services, though recent improvements have reduced this latency considerably. If the network is remote then it is advisable for the policy to reflect that the target network manpower can be called upon for a predefined duration for power resets, etc. Attempting this retrospectively through contractual alteration, if required, can be expensive and time consuming. If you rely on the distant network for support, ensure you have a telephone authentication system in place and don't fall victim to a social engineering attack. It's all too easy for an...

...Lab 2 – CSEC630 1. When running Snort IDS why might there be no alerts? When using Snort IDS, there are several modes that if configured properly, will generate alerts. Alerts are set by the user within the command prompt when initiating a rule set. There are five alerting options available with Snort IDS. According to (Roesch, 1999), Alerts may either be sent to syslog, logged to an alert text file in two different formats, or sent as Win-Popup messages using the Samba smbclient program. If there has been no alerts, the selected rule set was set may not have been enabled by the user. Another scenario where alerts may not occur is when another task is being performed. According to (Roesch, 1999) when alerting is unnecessary or inappropriate, such as when network penetrations tests are being performed. 2. If we only went to a few web sites, why are there so many alerts? Snort IDS performs numerous functions that would generate an alert. Alerts are generated based on any suspicious network activity. Although a user may have only visited 5 sites, snort may have generated 12 or more alerts that were generated due to anomalies detected from the 5 sites visited. 3. What are the advantages of logging more information to the alerts file? The advantage of logging additional information within the alerts file is that it can provide additional information as to the origination or source of what caused the alert. If the administrator is better informed on the...
