Network security" refers to any activity designed to protect the usability and integrity of your network and data. It includes both hardware and software technologies. Effective network security manages access to the network. It targets a variety of threats and stops them from entering or spreading on your network.
Network security combines multiple layers of defenses at the edge and in the network. Each network security layer implements policies and controls. Authorized users gain access to network resources, but malicious actors are blocked from carrying out exploits and threats.
How do I benefit from network security?
Digitization has transformed our world. How we live, work, play, and learn have all changed. Every organization that wants to deliver the services that customers and employees demand must protect its network. Network security also helps you protect proprietary information from attack. Ultimately it protects your reputation.
Web sites are unfortunately prone to security risks. And so are any networks to which web servers are connected. Setting aside risks created by employee use or misuse of network resources, your web server and the site it hosts present your most serious sources of security risk.
Web servers by design open a window between your network and the world. The care taken with server maintenance, web application updates and your web site coding will define the size of that window, limit the kind of information that can pass through it and thus establish the degree of web security you will have.
"Web security" is relative and has two components, one internal and one public. Your relative security is high if you have few network resources of financial value, your company and site aren't controversial in any way, your network is set up with tight permissions,
your web server is patched up to date with all settings done correctly, your applications on the web server are all patched and updated, and your web site code is done to high standards.
Your web security is relatively lower if your company has financial assets like credit card or identity information, if your web site content is controversial, your servers, applications and site code are complex or old and are maintained by an underfunded or outsourced IT department. All IT departments are budget challenged and tight staffing often creates deferred maintenance issues that play into the hands of any who want to challenge your web security.
This is a long form text area designed for your content that you can fill up with as many words as your heart desires. You can write articles, long mission statements, company policies, executive profiles, company awards/distinctions, office locations, shareholder reports, whitepapers, media mentions and other pieces of content that don’t fit into a shorter, more succinct space.
Articles – Good topics for articles include anything related to your company – recent changes to operations, the latest company softball game – or the industry you’re in. General business trends (think national and even international) are great article fodder, too.
Mission statements – You can tell a lot about a company by its mission statement. Don’t have one? Now might be a good time to create one and post it here. A good mission statement tells you what drives a company to do what it does.
Company policies – Are there company policies that are particularly important to your business? Perhaps your unlimited paternity/maternity leave policy has endeared you to employees across the company. This is a good place to talk about that.
Executive profiles – A company is only as strong as its executive leadership. This is a good place to show off who’s occupying the corner offices. Write a nice bio about each executive that includes what they do, how long they’ve been at it, and what got them to where they are.
Virtualization security is a broad concept that includes a number of different methods to evaluate, implement, monitor and manage security within a virtualization infrastructure / environment.
Typically, virtualization security may include processes such as:
Storage security is the group of parameters and settings that make storage resources available to authorized users and trusted networks - and unavailable to other entities. These parameters can apply to hardware, programming, communications protocols, and organizational policy.
Several issues are important when considering a security method for a storage area network (SAN). The network must be easily accessible to authorized people, corporations, and agencies. It must be difficult for a potential hacker to compromise the system. The network must be reliable and stable under a wide variety of environmental conditions and volumes of usage.
Protection must be provided against online threats such as viruses, worms, Trojans, and other malicious code. Sensitive data should be encrypted. Unnecessary services should be disabled to minimize the number of potential security holes. Updates to the operating system, supplied by the platform vendor, should be installed on a regular basis.
Redundancy, in the form of identical (or mirrored) storage media, can help prevent catastrophic data loss if there is an unexpected malfunction. All users should be informed of the principles and policies that have been put in place governing the use of the network.
Email security refers to the collective measures used to secure the access and content of an email account or service. It allows an individual or organization to protect the overall access to one or more email addresses/accounts.
An email service provider implements email security to secure subscriber email accounts and data from hackers - at rest and in transit.
Email security is a broad term that encompasses multiple techniques used to secure an email service. From an individual/end user standpoint, proactive email security measures include:
Similarly, a service provider ensures email security by using strong password and access control mechanisms on an email server; encrypting and digitally signing email messages when in the inbox or in transit to or from a subscriber email address.
It also implements firewall and software-based spam filtering applications to restrict unsolicited, untrustworthy and malicious email messages from delivery to a user’s inbox.
