Organizations benefit in several ways Full prevention enables a practical move from detection to data loss prevention. Explain general methods to mitigate common security threats to network devices, hosts, and applications Describe the functions of common security appliances and. Self educating system educates and alerts users without involving ITsecurity personnel. Inspect SSL Encrypted Traffic. Scan and secure SSL encrypted traffic passing through the gateway. When traffic is passed through, the gateway decrypts the traffic with the senders public key, inspects and protects, then re encrypts, sending the newly encrypted content to the receiver. For example, Gmail traffic is encrypted over HTTPS. If a user attaches a file to a message in Gmail, both the email and file will be inspected by DLP and be subject to the same policy as any clear unencrypted traffic. Granularly define exceptions for SSL inspection to protect user privacy and comply with corporate policy. Some encrypted content passing through the gateway should not be inspected, and therefore can be bypassed with a simple administrator policy definition. Network wide Protection Coverage. The Check Point DLP Software Blade is an in line, advanced data loss prevention solution for data transmitted over networks.

Network Security Using Cisco IOS IPS Introducing IDS and IPSThis chapter will introduce you to The underlying IDS and IPS technology that is embedded in the Cisco host and network based IDS and IPS solutions. Cisco IOS IPS using Cisco SDMIntrusion detection system IDS and intrusion prevention system IPS solutions form an integral part of a robust network defense solution. Maintaining secure network services is a key requirement of a profitable IP based business. Using Cisco products and technologies as examples, this chapter defines IDS and IPS and how these systems work. IDS and IPS work together to provide a network security solution. An IDS captures packets in real time, processes them, and can respond to threats, but works on copies of data traffic to detect suspicious activity by using signatures. This is called promiscuous mode. In the process of detecting malicious traffic, an IDS allows some malicious traffic to pass before the IDS can respond to protect the network. An IDS analyzes a copy of the monitored traffic rather than the actual forwarded packet. The advantage of operating on a copy of the traffic is that the IDS does not affect the packet flow of the forwarded traffic. The disadvantage of operating on a copy of the traffic is that the IDS cannot stop malicious traffic from single packet attacks from reaching the target system before the IDS can apply a response to stop the attack. An IDS often requires assistance from other networking devices, such as routers and firewalls, to respond to an attack. An IPS works inline in the data stream to provide protection from malicious attacks in real time. This is called inline mode. Unlike an IDS, an IPS does not allow packets to enter the trusted side of the network. An IPS monitors traffic at Layer 3 and Layer 4 to ensure that their headers, states, and so on are those specified in the protocol suite. However, the IPS sensor analyzes at Layer 2 to Layer 7 the payload of the packets for more sophisticated embedded attacks that might include malicious data. This deeper analysis lets the IPS identify, stop, and block attacks that would normally pass through a traditional firewall device. Bizhub 500 Manual De Partes Del. When a packet comes in through an interface on an IPS, that packet is not sent to the outbound or trusted interface until the packet has been determined to be clean. An IPS builds upon previous IDS technology Cisco IPS platforms use a blend of detection technologies, including profile based intrusion detection, signature based intrusion detection, and protocol analysis intrusion detection. The key to differentiating an IDS from an IPS is that an IPS responds immediately and does not allow any malicious traffic to pass, whereas an IDS allows malicious traffic to pass before it can respond. IDS and IPS technologies share several characteristics IDS and IPS technologies are deployed as sensors. An IDS or an IPS sensor can be any of the following devices A router configured with Cisco IOS IPS Software. An appliance specifically designed to provide dedicated IDS or IPS services. A network module installed in an adaptive security appliance, switch, or router. IDS and IPS technologies typically monitor for malicious activities in two spots Malicious activity is monitored at the network to detect attacks against a network, including attacks against hosts and devices, using network IDS and network IPS. Malicious activity is monitored on a host to detect attacks that are launched from or on target machines, using host intrusion prevention system HIPS. Host based attacks are detected by reading security event logs, checking for changes to critical system files, and checking system registries for malicious entries. IDS and IPS technologies generally use yes, signatures to detect patterns of misuse in network traffic, although other technologies will be introduced later in this chapter A signature is a set of rules that an IDS or IPS uses to detect typical intrusive activity. Signatures are usually chosen from a broad cross section of intrusion detection signatures, and can detect severe breaches of security, common network attacks, and information gathering. IDS and IPS technologies look for the following general patterns of misuse Atomic pattern In an atomic pattern, an attempt is made to access a specific port on a specific host, and malicious content is contained in a single packet. An IDS is particularly vulnerable to an atomic attack because until it finds the attack, malicious single packets are being allowed into the network. An IPS prevents these packets from entering at all. Composite pattern A composite pattern is a sequence of operations distributed across multiple hosts over an arbitrary period of time. Figure 6 1 shows a sensor deployed in IDS mode and a sensor deployed in IPS mode. The following are the steps that occur when an attack is launched in an environment monitored by an IDS Step 1. An attack is launched on a network that has a sensor deployed in IDS mode. Step 2. The switch sends copies of all packets to the IDS sensor configured in promiscuous mode, which is explained later in this section to analyze the packets. At the same time, the target machine experiences the malicious attack. Step 3. The IDS sensor, using a signature, matches the malicious traffic to the signature. Step 4. The IDS sensor sends the switch a command to deny access to the malicious traffic. Step 5. The IDS sends an alarm to a management console for logging and other management purposes. The following are the steps that occur when an attack is launched in an environment monitored by an IPS Step 1. An attack is launched on a network that has a sensor deployed in IPS mode configured in inline mode, which is explained later in this section. Step 2. The IPS sensor analyzes the packets as soon as they come into the IPS sensor interface. The IPS sensor, using signatures, matches the malicious traffic to the signature and the attack is stopped immediately. Traffic in violation of policy can be dropped by an IPS sensor. Step 3. The IPS sensor can send an alarm to a management console for logging and other management purposes. Table 6 1 lists some of the advantages and limitations of deploying an IDS platform in promiscuous mode. Table 6 1. Advantages and Limitations of Deploying an IDS in Promiscuous Mode. Advantage. Limitation. Deploying the IDS sensor does not have any impact on the network latency, jitter, and so on. IDS sensor response actions cannot stop the trigger packet and are not guaranteed to stop a connection. IDS response actions are typically better at stopping an attacker more than a specific attack itself. The IDS sensor is not inline and, therefore, a sensor failure cannot affect network functionality. IDS sensor response actions are less helpful in stopping email viruses and automated attackers such as worms. Overrunning the IDS sensor with data does not affect network traffic however, it does affect the capability of the IDS to analyze the data. Users deploying IDS sensor response actions must have a well thought out security policy combined with a good operational understanding of their IDS deployments. Users must spend time to correctly tune IDS sensors to achieve expected levels of intrusion detection. Being out of band OOB, IDS sensors are more vulnerable to network evasion techniques, which are the process of totally concealing an attack. Table 6 2 lists some of the advantages and limitations of deploying an IPS platform in inline mode. Table 6 2. Advantages and Limitations of Deploying an IPS in Inline Mode. Advantage. Limitation. You can configure an IPS sensor to perform a packet drop that can stop the trigger packet, the packets in a connection, or packets from a source IP address. An IPS sensor must be inline and, therefore, IPS sensor errors or failure can have a negative effect on network traffic.
