Unified Threat Management (UTM) or Unified Security Management (USM), is a solution in the network security industry, and since 2004 it has gained currency as a primary network gateway defense solution for organizations.
In theory, UTM is the evolution of the traditional firewall into an all-inclusive security product able to perform multiple security functions within one single appliance: network firewalling, network intrusion prevention and gateway antivirus (AV), gateway anti-spam, VPN, content filtering, load balancing, data leak prevention and on-appliance reporting.

Firewall is a network security system that controls the incoming
and outgoing network traffic based on an applied rule set. A firewall establishes a barrier between a trusted, secure internal network and another network (e.g., the Internet) that is assumed not to be secure and trusted Stand-alone firewalls exist both as firewall software appliances to run on general purpose or standard industry hardware, and as hardware-based firewall computer appliances.

Firewall protection is the one that controls and monitors the network traffic whether it is incoming or outgoing on predetermined rules of security. It is basically a barrier or a shield applied specifically to save your PC, phone or tablet from the malwares of external world that exist in abundance on the internet.
While computer systems today have some of the best security systems ever, they are more vulnerable than ever before.
This vulnerability stems from the world-wide access to computer systems via the Internet.
Computer and network security comes in many forms, including encryption algorithms, access to facilities, digital signatures, and using fingerprints and face scans as passwords.
Forming a team of 3 members, we did a research on Campus Area Network Security. It was for our Computer Networks Project. At the time of submitting the project and research paper, we gave a presentation. I made this slide for that presentation.

3.8 Ways to Establish Secure Protocols in a Digital Organization.pdfBelayet Hossain
How to establish secure protocols in a digital organization? In recent years, massive cybercrimes have targeted businesses all around the world. Organizations are constantly subjected to security breaches, including data leaks, broken authentication, database hacking, malware infestations, and denial of service attacks on their networks, web applications, and servers.

Network security presentation that briefly covers the aspect of security in networks. The slide consists of procedural steps for network security then some of the important network security components are described. To give it a practical approach, attacks on networks are also covered.
Cyber Warfare is the current single greatest emerging threat to National Security. Network security has become an essential component of any computer network. As computer networks and systems become ever more fundamental to modern society, concerns about security has become increasingly important. There are a multitude of different applications open source and proprietary available for the protection +-system administrator, to decide on the most suitable format for their purpose requires knowledge of the available safety measures, their features and how they affect the quality of service, as well as the kind of data they will be allowing through un flagged. A majority of methods currently used to ensure the quality of a networks service are signature based. From this information, and details on the specifics of popular applications and their implementation methods, we have carried through the ideas, incorporating our own opinions, to formulate suggestions on how this could be done on a general level. The main objective was to design and develop an Intrusion Detection System. While the minor objectives were to; Design a port scanner to determine potential threats and mitigation techniques to withstand these attacks. Implement the system on a host and Run and test the designed IDS. In this project we set out to develop a Honey Pot IDS System. It would make it easy to listen on a range of ports and emulate a network protocol to track and identify any individuals trying to connect to your system. This IDS will use the following design approaches: Event correlation, Log analysis, Alerting, and policy enforcement. Intrusion Detection Systems (IDSs) attempt to identify unauthorized use, misuse, and abuse of computer systems. In response to the growth in the use and development of IDSs, we have developed a methodology for testing IDSs. The methodology consists of techniques from the field of software testing which we have adapted for the specific purpose of testing IDSs. In this paper, we identify a set of general IDS performance objectives which is the basis for the methodology. We present the details of the methodology, including strategies for test-case selection and specific testing procedures. We include quantitative results from testing experiments on the Network Security Monitor (NSM), an IDS developed at UC Davis. We present an overview of the software platform that we have used to create user-simulation scripts for testing experiments. The platform consists of the UNIX tool expect and enhancements that we have developed, including mechanisms for concurrent scripts and a record-and-replay feature. We also provide background information on intrusions and IDSs to motivate our work.
NETWORK INTRUSION DETECTION AND COUNTERMEASURE SELECTION IN VIRTUAL NETWORK (...ijsptm
Intrusion in a network or a system is a problem today as the trend of successful network attacks continue to
rise. Intruders can explore vulnerabilities of a network system to gain access in order to deploy some virus
or malware such as Denial of Service (DOS) attack. In this work, a frequency-based Intrusion Detection
System (IDS) is proposed to detect DOS attack. The frequency data is extracted from the time-series data
created by the traffic flow using Discrete Fourier Transform (DFT). An algorithm is developed for
anomaly-based intrusion detection with fewer false alarms which further detect known and unknown attack
signature in a network. The frequency of the traffic data of the virus or malware would be inconsistent with
the frequency of the legitimate traffic data. A Centralized Traffic Analyzer Intrusion Detection System
called CTA-IDS is introduced to further detect inside attackers in a network. The strategy is effective in
detecting abnormal content in the traffic data during information passing from one node to another and
also detects known attack signature and unknown attack. This approach is tested by running the artificial
network intrusion data in simulated networks using the Network Simulator2 (NS2) software.

Abstract-Denial-of-Service attacks, a type of attack on a network that is designed to bring the network to its knees by flooding it with useless traffic. Many Dos attacks, such as the Ping of Death ,Teardrop attacks etc., exploit the limitations in the TCP/IP protocols. like viruses, new Dos attacks are constantly being dreamed up by hackers.So the users have to take own effort of a large number of protected system such as Firewall or up-to-date antivirus software. . If the system or links are affected from an attack then the legitimate clients may not be able to connect it.. This detection system is the next level of the security to protect the server from major problems occurs such as Dos attacks, Flood IP attacks, and also the Proxy Surfer. So these kinds of anonymous activities barred out by using this Concept.

Network security is a dynamic art, with dangers appearing as fast as black hats can exploit vulnerabilities. While there are basic “golden rules” which can make life difficult for the bad guys, it remains a challenge to keep networks secure. John Chambers, Executive Chairman of Cisco, famously said “there are two types of companies: those that have been hacked, and those who don’t know they have been hacked”. The question for most organizations isn’t if they’re going to be breached, but how quickly they can isolate and mitigate the threat. In this paper, we’ll examine best practices for effective cybersecurity – from both a proactive (access hardening) and reactive (threat isolation and mitigation) perspective. We’ll address how network automation can help minimize cyberattacks by closing vulnerability gaps and how it can improve incident response times in the event of a cyberthreat. Finally, we’ll lay a vision for continuous network security, to explore how machine-to-machine automation may deliver an auto-securing and self-healing network.

3. Why is this an issue?
Traditional firewalls cannot detect these new applications they rely on port numbers or protocol
identifiers to recognize and categorize network traffic and to enforce policies related to such
traffic
Apps that use specific port numbers or protocols make it easy for network administrators to
block unwanted traffic, but browser-based applications often use only two port numbers, each
associated with a protocol vital to user productivity and responsible for the bulk of Internet
traffic today
This means that all traffic from browser-based apps looks exactly the same to traditional
firewalls; they can’t differentiate between applications, so there is no easy way to block bad,
unwanted, or inappropriate programs whilst permitting desirable or necessary apps to proceed
unhindered

4. Unified Threat Management (UTM)
Unified threat management (UTM) is an approach to security management that allows an administrator to
monitor and manage a wide variety of security-related applications and infrastructure components through a
single management console.
•
UTM delivers a flexible, future-ready solution to meet the challenges of today’s networking
environments.
•
UTMs represent all-in-one security appliances that carry a variety of security capabilities including
firewall, VPN, gateway anti-virus, gateway anti-spam, intrusion prevention, content filtering, bandwidth
management, application control and centralized reporting as basic features.
•
The UTM has a customized OS holding all the security features at one place.
4
5. UTM
The best UTM solutions include the following core security functions:
Network firewalls perform stateful packet inspection
IPS detects and blocks intrusions and certain attacks
Application control provides visibility and control of application behaviour and content
VPN enables secure remote access to networks
Web filtering halts access to malicious, inappropriate, or questionable websites and online
content
IPv6 support in all network security functions protects networks as they migrate from IPv4 to IPv6
Support for virtualized environments, both virtual domains and virtual appliances
5
7. UTM vs. NGFW
The difference between UTMs and NGFWs is actually minimal. The only tangible difference that
may be found involves their respective throughput ratings; devices marketed as UTMs typically
have a lower throughput rating and are marketed to small and medium-sized businesses, while
devices that maintain a higher throughput rating are typically marketed as NGFWs. In terms of
functionality, the two devices are almost carbon copies.
NGFW
NGFWs were designed to perform intrusion prevention and deep packet inspection while many
of the other features mentioned above were offloaded to other devices to conserve network
throughput and thereby better serve an enterprise network. More recently, NGFWs added
application firewall features, a dynamic new capability that in many cases has allowed enterprises
to consolidate and use a single device to protect their applications and core networks. At present,
however, multi-Gigabit LAN speeds are commonplace, and the need for a device that only
performs certain NGFW functions has become obsolete.
7
8. Key Features & Capabilities of UTM
The standard and Next-Generation Network Firewall (NGFS) functions include:
•
The ability to track and maintain state information for communications to determine the source
and purpose of network communications.
•
The ability to allow or block traffic based on configured policy (which can be integrated with the
state information).
•
The ability to perform Network Address Translation (NAT) and Port Address Translation(PAT).
•
The ability to perform application aware network traffic scanning, tracking and control.
•
The ability to optimize a network connection (i.e. using TCP optimization).
8
9. Advantages of Using a Unified Threat Management
•
Less Complexity- The all-in-one approach simplifies several things, such as product integration,
product selection and ongoing support.
•
Ease of Deployment- As lesser human intervention is required, it is easy to install and
maintain. One can get the product installed by finding a reputed vendor online.
•
The Black Box Approach- Users have a habit of playing with things. Here, the black box
approach puts a restriction on the damage that users can cause. This diminishes trouble and
enhances network security.
•
Integration Capabilities- The appliances can be distributed easily at remote sites. In such a
scenario, a plug and play device can be set up and handled remotely. This type of management
is interactive with firewalls that are software- based.
9
10. Disadvantages of Unified Threat Management
Lower performance
Single point of failure.
Vendor lock-in.
Difficult to scale in large environments.
Limited feature set compared to point product alternatives.
10
12. WEB APPLICATION FIREWALL
A web application firewall (WAF) is an appliance, server plug-in, or filter that applies a set of
rules to an HTTP conversation. The effort to perform this customization can be significant and
needs to be maintained as the application is modified.
Web application firewall is a computer networking firewall operating at the application layer of a
protocol stack and is also known as a proxy-based or reverse-proxy firewall.
WAF solutions are capable of preventing attacks that network firewalls and intrusion detection
systems can't, and they do not require modification of application source code.
12
13. 13
Problem WAF Countermeasure
Cookie protection +
+
Cookies can be signed
Cookies can be encrypted.
Information leakage + Cloaking filter, outgoing pages can
be cleaned (error messages,
comments, undesirable information).
Session fixation = Can be prevented if the WAF
manages the sessions itself
File upload + Virus check (generally via external
systems)
SSL + SSL connection possible from WAF
to application.
Cross-site tracing + Restriction of the HTTP method
HTTP request smuggling + Is prevented via strict testing of the
conformity to standards of each
request.
14. ATTACKS PREVENTED BY WEB APPLICATION FIREWALL
SQL INJECTION
CROSS-SITE SCRIPTING (XSS)
DOS ATTACKS AND DDOS ATTACKS
SESSION HIJACKING ATTACKS
14
15. SQL INJECTION
A SQL injection attack consists of insertion or "injection" of a SQL query via the input data from
the client to the application.
A successful SQL injection exploit can read sensitive data from the database, modify database
data (Insert/Update/Delete), execute administration operations on the database (such as
shutdown the DBMS).
SQL injection attacks allow attackers to spoof identity, tamper with existing data, cause
repudiation issues such as voiding transactions or changing balances, allow the complete
disclosure of all data on the system
SQL Injection is very common with PHP and ASP applications due to the prevalence of older
functional interfaces
15
16. CROSS-SITE SCRIPTING (XSS)
Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected
into otherwise benign and trusted web sites.
XSS attacks occur when an attacker uses a web application to send malicious code, generally in
the form of a browser side script, to a different end user.
Cross-Site Scripting (XSS) attacks occur when
Data enters a Web application through an untrusted source, most frequently a web request.
The data is included in dynamic content that is sent to a web user without being validated for
malicious content.
16
18. DOS ATTACKS AND DDOS ATTACKS
The Denial of Service (DoS) attack is focused on making a resource (site, application, server)
unavailable for the purpose it was designed.
Sometimes the attacker can inject and execute arbitrary code while performing a DoS attack in
order to access critical information or execute commands on the server.
Denial-of-service attacks significantly degrade the service quality experienced by legitimate users.
These attacks introduce large response delays, excessive losses, and service interruptions,
resulting in direct impact on availability.
18
19. HOW DOS ATTACKS PERPETRATED?
A DoS attack can be perpetrated in a number of ways:
Consumption of computational resources, such as bandwidth, memory, disk space, or
processor time.
Disruption of configuration information, such as routing information.
Disruption of state information, such as unsolicited resetting of TCP sessions.
Obstructing the communication media between the intended users and the victim so that they
can no longer communicate adequately.
19
20. SESSION HIJACKING ATTACKS
The Session Hijacking attack consists of the exploitation of the web session control mechanism,
which is normally managed for a session token. Because http communication uses many different
TCP connections, the web server needs a method to recognize every user’s connections.
The Session Hijacking attack compromises the session token by stealing or predicting a valid
session token to gain unauthorized access to the Web Server.
The session token could be compromised in different ways :
Predictable session token
Session Sniffing
Client-side attacks (XSS, malicious JavaScript Codes, Trojans, etc)
Man-in-the-middle attack
Man-in-the-browser attack

THREE PROTECTION STRATEGIES
1. External patching
Also known as "just-in-time patching" or "virtual patching").
1. Negative security model
Looking for bad stuff.
Typically used for Web Intrusion Detection.
Easy to start with but difficult to get right.
1. Positive security model
Verifying input is correct.
Usually automated, but very difficult to get right with applications that change.
It's very good but you need to set your expectations accordingly.
