OpenDNS in Cyber Security Threat Mitigation

The 21st century gets marked with a tremendous growth in the use of sophisticated technology. Advancement in technology contributes positively to the realization of core business objectives across the world despite the associated challenges. Cyber-attacks are on the rise and the damage caused to small and large enterprises necessitates measures to protect employees and corporate business. Information Technology Officers are on the outlook for the best possible solution aimed at combating cyber security incidents (Delgado 14). Previous cyber security concerns reported across the globe lead to the identification of means to streamline business operations free from information vulnerabilities. The concept of cyber security software in the name of Open DNS will receive discussion as means of protecting business information from unwary activities like phishing in company X of more than one thousand employees who use IT related devices.

Open DNS gets preferred by many organizations as a powerful protection tool for malware and web filtering whether the employees are on or off the corporate network. Company X lives with worries about an attack on employees by receiving emails that target the business or specific individuals in the firm. The reception of the email by an employee gets structured to contain a fraudulent website link thereby allowing an attacker to steal login details. OpenDNS counters phishing activities that target individuals or masses in a company. It includes advanced predictive intelligence features that expose infrastructure on which phishing sites get hosted. This tool also integrates a feature called Phish Tank data that counters the vulnerabilities in business systems, therefore, protection against unauthorized access (Cisco 2). It offers an advanced platform in thwarting phishing by having a big data analytics carry out prediction to uncover sudden attack, thus automatically blocking business intrusion (Bruzzese 9). OpenDNS performs a comparison of corporate security activity to the cyber security activities in the world and finally investigates on the likelihood of an emergency source related to internet attack.

Employees that surf the web at any given system utilize a Domain Name System that communicates with the web server to get desired content. The DNS servers act as intermediaries between the business browser platform and the website content thereby exposing employees to phishing attackers (Geier 12). Additional tools are integrated into DNS users, and the OpenDNS feature provides malware and phishing blocking to protect company information. OpenDNS tool blocks sites that contain viruses and other scams that seem detrimental to business activities (Geier 17). Its usage as a cyber-security solution prevents dangerous content, thus shielding business operations against internet attack. This tool offers a form of an automatic or a preconfigured content filtering technique that gives results in the event the attack site tries to launch. OpenDNS mitigates the threat on phishing by trending on internet activity blocking different activity regardless of the protocol or the app used, thus preventing the loading of a phishing site. Application of huge data analytics as an intelligence measure in threat detection improves vigilance on various fronts and eventually safeguarding company information and activities (Bruzzese 21).

The OpenDNS used for offering business service gets known as Umbrella and provides an advanced security against data vulnerabilities in an enterprise environment (Richard 16). The OpenDNS umbrella service caters for larger services where advanced features and functionality get requirement. The company will require DNS servers provided by the OpenDNS platform rather than those offered by Internet Service Provider (ISP) (Cobb 25). Other conditions include the Cache Check tool and the Smart Cache that allow the users access to websites affected by servers failures. Company Company X will have to manually set the OpenDNS by configuring the service on the company server or router that doesn’t necessitate any hardware or software requirements. The implementation of the OpenDNS requires no major additional hardware or software facilities to the system, therefore, ease of application.

The network administrators in company X will consider the effect of the implementation of the OpenDNS before taking it on a live system in the workplace. The system administrators have to understand how OpenDNS works through filtering by blocking multiple Internet Protocol ranges where necessary (Richard 27). The definition of blacklists and white lists in surfing will receive customization according to the selected company policy that employees need to get trained on (Richard 25). Network administrators require knowledge on how to customize the control panel with contact details alongside logos to communicate blocked category details to the end-users in a friendly manner.

The principal of information security offers wide-ranging concepts regarding the discipline of information security that aims at guarding the business against attack by outsiders. The concepts offer the network users in a company to have a grasp on how the system works including the server thereby increasing security survival chances (Whitman 28). Administrators and employees should understand the running of the scheme and how to recognize the alterations to ensure they counter phishing activities. In-depth, defense should get fostered to place multiple forms of protection between the asset and the phishing attackers. Security technologies outlined in the principles of information technology align with what is expected of OpenDNS in protection against intrusion due to phishing activities (Whitman 10).

The total cost of owning OpenDNS, especially the cloud, is very low. The lack of hardware and software installations means there are no software to maintain and nothing to update. Focus on the business becomes easy with little investment on the training of network administrators on the pre-configurations.

In summary, company X will get well served with OpenDNS that provides vigilance from all fronts since the pool of employees access multiple sites. The provision of huge data analytics by OpenDNS guarantees the information protection to a high degree as compared to other cyber security systems. Threat detection gets monitored by tracing threat activities on a daily basis. OpenDNS implementation and maintenance cost are cheap, hence ease of adoption.
