Network security a few years ago was not a part of an organization's annual budget where traditional wired computers sent secure information to the server placed in an isolated network and traditional routers with a basic firewall performed the job of securing an organization's network. This was a primitive age of network security when network security was little known and considered as an avoidable expense.

The Distributed Office Scenario: A number of critical issues and ongoing developments are driving both a need for better network security and for network optimization between office locations.

network optimization

The performance and security needs of corporate networks have evolved greatly in the last five years, driven by changing business and economic demands, different patterns of working and a continuous stream of new technologies. In this environment of 'Business 2.0', the network is the organization's vital beating heart, a strategic business tool used by companies to drive significant competitive advantage.

The challenges facing grade school educators are greater than ever before. The standards for academic achievement and the expectations of students' families continue to climb. At the same time, education budgets are tighter. Schools' technology infrastructures are caught in the middle, requiring K-12 IT administrators to literally do more with less. Networked resources have addressed some qualitative issues. Online instruction materials and classroom management services supplement teachers' capabilities and free them from administrative chores.

Awareness of a network vulnerability often comes by a system monitoring alert, log file review or vendor press release. As a security administrator, your job is to quickly decide if it poses a real threat to your network, how to remedy that threat, and the priority for action. Your operational challenge is linking an alarm to actual network activity by specific users. The lack of specific data often forces security professionals to guess at the degree of exposure, or whether a breach actually occurred. Without sufficient network forensics data, your ability to identify the scope of a security event or verify compliance with security policy is ineffective.

Retail is more competitive today than ever before. Whether selling out of a single storefront, a network of kiosks, through a global retail enterprise with multiple store locations or online, today's retailers increasingly leverage technology to provide the decisive edge. While new technologies such as broadband, VoIP or wireless can open your network resources to prospects, customers, partners, vendors and staff , they also create new channels for malicious or inadvertent threats.

Network security has evolved and point solutions have arisen to deal with them, ranging from content filtering to IPS to Integrated Next-Generation Firewalls. Management of multipledevices has become expensive and complex. Instead of buying, connecting and managing a loose patchwork of point solutions, now you can get all you need in one consolidated Next-Generation Firewall.

Federal cybersecurity transformation really took off following a year-long cybersecurity pilot test conducted by the State Department, which implemented continuous monitoring and risk-based scoring to track and manage IT vulnerabilities. Automated data collection helped the State Department reduce overall risk on a key unclassified network by 90 percent.

What IT organizations need is a single solution that can effectively address both problems, by controlling all application traffic and mitigating all corresponding threats. Fortunately, Next-Generation Firewalls with application intelligence, control and visualization capabilities, such as the SonicWALL E-Class Network Security Appliance (NSA) Series, can leverage the benefits of the cloud securely and with confidence. Next-Generation Firewalls allow IT organizations to identify and enforce policy-based controls on both cloud-based and on-premise applications in use, and securely identify users regardless of port or protocol. These solutions can help manage bandwidth for cloud applications and users, as well as eliminate the malware and productivity threats that come along with cloud consumption.

With YouTube for Schools enabled by a SonicWALL® Next-Generation Firewall, school administrators and teachers can log in and watch any video. Students cannot access the administrator level, and they can only watch YouTube EDU videos plus videos their school has added. Any web requests by students to go to the regular YouTube.com site get automatically redirected to YouTube EDU. All comments and related videos are disabled and search is limited to YouTube EDU videos. All schools get access to all of the YouTube EDU content, but teachers and administrators can also create playlists of videos that are viewable only within their school's network.
