(Unified Threat Management) UTM What is (Unified Threat Management) UTM?
Unified Threat Management (UTM) is a security solution that consolidates multiple security features to reduce total cost of ownership (TCO) and offers a single point of defense against a range of security vulnerabilities like viruses, worms, malware, spyware, and other network attacks.
These capabilities, better known as a Next-Generation Firewall (NGFW), provide multiple security features and services in a single device or service on the network, protecting users from security threats in a simplified way. NGFW includes functions such as anti-virus, anti-spam, content filtering, and web filtering.
UTM Explained
Typical Unified Threat Management (UTM) feature sets fall into three main subsets, all within UTM: firewall/intrusion prevention system/virtual private network, secure web gateway security (URL filtering, web antivirus [AV]) and messaging security (anti-spam, mail AV).
UTM enables security teams to efficiently monitor security risks across geographically distributed locations and rapidly respond to threats while reducing the total cost of owning and maintaining different products.
How does UTM work?
UTM consolidates various core security functions and reduces the need for deploying different point products. UTM offers centralized security monitoring and management by leveraging different security components to scan the traffic entering and leaving the network. It uses deep packet inspection (DPI) to gain packet-level visibility into all the data moving across the network and blocks malicious or compromised inward and outward traffic.
With a consolidation of security functions like firewall, antivirus, IPS, DLP, etc., under a single UTM solution, the security team gets a holistic view of overall security posture, thereby reducing management complexity.
What are the benefits of UTM?
UTM consolidates the number of security point products, which helps IT teams to efficiently monitor and manage overall network security and reduce operational expenses. The following are the significant benefits of deploying UTM:
- Centralized security management: Your network needs protection from numerous threat vectors targeting different components of the network. Without UTM, the security team would need different point products to safeguard the network, thereby increasing complexity. UTM offers a consolidated view of overall security health, combining insights from different products and enabling the security team to manage and protect multiple geographically distributed locations from advanced threats.
- Cost savings: Replacing multiple products with UTM results in cost savings on many fronts, including fewer physical devices resulting in reduced hardware procurement, maintenance, training, and dedicated staff costs.
- Rapid response: UTM offers an efficient way to process data coming from different UTM components, derive meaningful insights, and take rapid action, all using a single dashboard.
- Compliance support: Enterprises are required to maintain a high level of data security and access control to meet different compliance requirements like GDPR, HIPPA, PCI DSS, etc. With a unified security solution like UTM, enterprises can efficiently deploy a robust set of security features in one solution that can meet compliance requirements.
What are the core functions in a UTM?
UTM consolidates a range of security functions into one solution. The primary functions or features under UTM can be grouped in the following categories:
- Firewall: A network firewall is hardware or software that restricts and permits the flow of traffic between networks. Network firewalls help prevent cyberattacks by enforcing policies that block unauthorized traffic from accessing a secure network.
- Antivirus and anti-malware: Antivirus or anti-malware tools scan the traffic flowing through network devices and reduces any kind of malicious vectors like viruses, worms, trojans, etc.
- Virtual Private Network (VPN): VPN provides secure remote access to the corporate network by encrypting the data and enabling the transfer of sensitive data over less secure networks, like the internet.
- URL filtering or web filtering: Blocks access to websites if the requested URL from end devices matches against a continuously updated database of known malicious sites.
- Intrusion Detection and Prevention (IDS/IPS): Intrusion prevention detects malicious activities and performs actions when an intrusion is detected. It inspects all traffic going through the network, using both signature based and pattern based inspection, leveraging a library of known threats. If an intrusion matches a signature pattern, the system takes action. Intrusion detection provides threat intelligence about malicious activities including command and control, ransomware, phishing, malware, spyware, trojans, and exploit kits.
- Data Loss Prevention (DLP): DLP helps protect sensitive data within a network by monitoring, detecting, and blocking potential data breaches or unauthorized access.
- Traffic segmentation: Regulates traffic flow across the network and provides role-based access to resources.
To secure the network from advanced security threats, UTM can be combined with Security Service Edge (SSE) to expand the security monitoring and response.
How does next generation firewall (NGFW) protect users and networks?
IT teams are constantly faced with the challenge of protecting their company’s productivity and digital assets against evolving and sophisticated threats, including spam and phishing attacks, viruses, trojans and spyware infected files, unapproved website access, and unapproved content. They must address these challenges with limited budgets and resources. Having multiple separate devices, each designed to perform a specialized function such as spam filtering, web content filtering, or antivirus protection does not make this task easier. Rather, it adds to the cost and complexity of managing multiple boxes and multiple operating systems.
An NGFW is a single system that provides the answer to all of these challenges and more:
- It secures the network from viruses, malware, or malicious attachments by scanning the incoming data using Deep Packet Inspection.
- It prevents attacks before they enter the network by inspecting the packet headers.
- It prevents access to unwanted websites by installing enhanced web filtering.
- It provides ability to update automatically with the latest security updates, anti-virus definitions, and new features so that less manual intervention is required beyond initial set-up.
- It enables administrators to manage a wide range of security functions with a single management console.
What’s the difference between NGFW and UTM?
Both UTM and NGFW consolidate network security functions in a single solution. There is no defined difference between these two as the definition of both solutions has evolved over time and in response to market needs. NGFW offer protection at the application level and leverage the latest technology to enable strong overall network security.
HPE and Unified Threat Management (UTM)
HPE offers UTM via its HPE Juniper Networking Next Generation Firewall which consolidates all the significant functions of UTM.
HPE Networking also consolidates various UTM functions in its management platform—HPE Aruba Networking Central.
HPE Juniper Networking SRX Series Next-Generation Firewalls and the vSRX Virtual Firewall include outstanding content security against malware, viruses, phishing attacks, intrusion attempts, spam, and other threats through unified threat management, protecting against network-level attacks, application-level attacks, and content-based attacks. The components provided in NGFW systems include:
- Anti-spam—Tags or blocks unwanted e-mail traffic by scanning inbound and outbound SMTP e-mail traffic. Antispam filtering allows you to use both a third-party server-based spam block list (SBL) and to optionally create your own local allow list and deny list for filtering against e-mail messages. for filtering against e-mail messages.
- Anti-virus—Uses a scanning engine and virus signature databases to protect against virus-infected files, worms, trojans, spyware, and other malware over POP3 HTTP, SMTP, IMAP, and FTP protocols. By using Juniper Advanced Threat Prevention (ATP), you can combine traditional signature-based detection with latest anti-malware technologies to detect threats and mitigate them.
- Content Filtering—Provides basic data loss prevention functionality. Content filtering filters traffic based on MIME type, file extension, and protocol commands. You can also use the content filter module to block ActiveX, Java Applets, and other types of content. Content filtering does not require a separate license.
- Web Filtering—Provides URL filtering capability by using either a local Websense server or Internet-based SurfControl server. Web filtering is critical as a service for tracking productivity and corporate user behavior.
