O2 Networks provides high-level security consulting and solutions for our clients. Our consultants operate actively in the security space with its constantly changing threats and demands.
Network security is more important than ever. Hackers are becoming more aggressive and creative in their attacks. The rapid adoption of wireless networking and IP telephony creates a new, dynamic security environment that opens up the network to attack.
O2 Networks has extensive experience in these evolving areas of security:
Firewalls mediate access between users applications and services. Firewalls are continually evolving, moving from traditional stateful inspection devices through to next generation unified threat management solutions that provide application and user aware controls, including antivirus, anti-SPAM, malware protection, content filtering, traffic management and policing, and VPN termination.
O2 Networks build multi-tiered firewall solutions using a wide variety of vendor solutions, aligning your businesses security requirements with the best available security solution.
Intrusion Prevention Systems (IPS) provide close and detailed analysis of critical network segments, identifying malicious traffic and applications and mitigating these threats in real time. IPS solutions are deployed inline in key network segments including network perimeters and on B2B services, and ensure constant adherence to your security policy across your network.
IPS solutions involve substantial tuning to optimise their performance and to reduce the possibility of false positives and false negatives. O2 Networks have worked with all leading IPS vendors, deploying their solutions as a component in the varied network security platforms integrated into our customer environments.
Networks and security elements generate substantial logs on a daily basis, causing many organisations to drown in the detail. By deploying a centralised event management and correlation system, you can drill into unstructured data and reach meaningful conclusions about your organisation’s security.
O2 Networks work with industry leading technology solutions to find that needle in a haystack and get you back in control of your network assets.
Traditional IPS solutions are network perimeter focused and depend upon a constantly updating set of signatures to detect when something is amiss in your network. On the other hand, network based anomaly detection (NBAD) systems allow for centralised analysis and reporting of atypical network behaviours, spotting that zero day attack or new worm on your network before it brings your systems to a halt.
O2 Networks use solutions from key vendors in this space to generate real value almost immediately upon connection to your network.
Remote access solutions have evolved considerably from the days of dial up or software based IPSec VPN connections. O2 Networks has a distinguished background building best of breed remote access solutions covering the full gamut of solutions from SSL VPNs to IPSec VPNs, from published applications to branch office in-a-box solutions.
Regardless of the connectivity mechanisms (wired, wireless, 3G, dial up), O2 Networks’ consultants have delivered a solution to meet customer requirements in every type of customer environment.
With the advent of robust application level attacks, traditional firewall and IPS solutions just don’t cut it anymore. Automated scanners and bot programs web scrape site data for subsequent manipulation or re-publishing.
Security regulations, including PCI DSS, require organisations to use application firewalls to protect against these attacks. Some of the most serious security threats come from attacks that target vulnerabilities in enterprise applications that aren’t visible below layer 7 of the OSI stack.
Web application firewalls allow for protection from zero day attacks and block attacks against vulnerable applications that may take an inordinate amount of time to recode to overcome coding faults. O2 Networks work extensively in the online and finance industries to deploy web application firewall solutions that protect organisations in the most critical parts of their customer and internal facing application infrastructures.
When publishing applications or services to the Internet, traditional role based access control solutions quickly become limiting with respect to scaling and distribution of user credentials. Two-factor authentication is based on something you know (a password or PIN) and something you have (an authenticator), providing a much more reliable level of user authentication than reusable passwords.
Two factor authentication solutions can be reliably provisioned and simply distributed to remote users, significantly improving the resistance of an application or authentication system from malicious attacks.
To further bolster application security, certificate based solutions can be deployed to provide for machine or user level client-server certification authentication, often deployed within 802.1X and NAC solutions.
O2 Networks has been deploying two factor authentication and PKI solutions into our client base for many years. O2 Networks consultants can quickly appraise your security requirements and recommend a suitable solution that offers optimal security with the simplest footprint, so you can simply and easily manage your selected technology platform.
As more organisations move to deploying web facing applications and services, the likelihood of your network suffering from some form of business disruptive denial of service (DoS) attack increases exponentially.
O2 Networks leverage industry-leading solutions to spot attacks in progress, or to provide a clean feed to ensure your business critical applications do not degrade in the face of bombardment.
Deploying a wireless network is a key functional component of any organisation’s connectivity requirements. The introduction of wireless networking drives productivity but opens your organisation up to external parties attempting to crash your network at the same time.
Guest access and kiosk solutions can be delivered in a secure and highly scalable manner to allow for pervasive connectivity to guests and contractors alike. O2 Networks has extensive experience in deploying centrally managed, highly secure wireless networks which allow for real time alerts to the changing conditions of your wireless network.
