Such a thing might well be impractical, or impossible to find and/or maintain. What security is though is risk reduction, not risk elimination. It's about employing all the appropriate controls available to you, within reason, that allow you to improve your overall posture reducing the odds of making yourself a target, subsequently getting hacked. Often, a good place to start when it comes to website security is your hosting environment. Today, there are a number of options available to you, and while hosts offer security to a certain level, it's important to understand where their responsibility ends and yours begins. Here is a good article explaining the complicated dynamic between web hosts and the security of your website. A secure server protects the privacy, integrity, and availability of the resources under the server administrator's control.
Qualities of a trusted web host might include. Readily discusses your security concerns and which security features and processes they offer with their hosting. Provides the most recent stable versions of all server software. Provides reliable methods for backup and recovery.
Decide which security you need on your server by determining the software and data that needs to be secured. The rest of this guide will help you with this.
Website Applications. It's easy to look at web hosts and pass the responsibility of security to them, but there is a tremendous amount of security that lies on the website owner as well. Web hosts are often responsible for the infrastructure on which your website sits, they are not responsible for the application you choose to install.
To understand where and why this is important you must understand how websites get hacked, Rarely is it attributed to the infrastructure, and most often attributed to the application itself (i. Security Themes. Keep in mind some general ideas while considering security for each aspect of your system.

Press installation, consider using Subversion to make management easier.
Reporting Security Issues. If you think you have found a security flaw in Word.
Press, you can help by reporting the issue. See the Security FAQ for information on how to report security issues.
If you think you have found a bug, report it. See Submitting Bugs for how to do this. You might have uncovered a vulnerability, or a bug that could lead to one. Web Server Vulnerabilities. The web server running Word. Press, and the software on it, can have vulnerabilities. Therefore, make sure you are running secure, stable versions of your web server and the software on it, or make sure you are using a trusted host that takes care of these things for you.
If you're on a shared server (one that hosts other websites besides your own) and a website on the same server is compromised, your website can potentially be compromised too even if you follow everything in this guide. Be sure to ask your web host what security precautions they take. Network Vulnerabilities. The network on both ends - - the Word. Press server side and the client network side - - should be trusted.
That means updating firewall rules on your home router and being careful about what networks you work from. An Internet cafe where you are sending passwords over an unencrypted connection, wireless or otherwise, is not a trusted network. Your web host should be making sure that their network is not compromised by attackers, and you should do the same. Network vulnerabilities can allow passwords and other sensitive information to be intercepted. Passwords. Many potential vulnerabilities can be avoided with good security habits. A strong password is an important aspect of this. The goal with your password is to make it hard for other people to guess and hard for a brute force attack to succeed.
Many automatic password generators are available that can be used to create secure passwords. Word. Press also features a password strength meter which is shown when changing your password in Word.
Press. Use this when changing your password to ensure its strength is adequate. Things to avoid when choosing a password. Any permutation of your own real name, username, company name, or name of your website. A word from a dictionary, in any language. A short password. Any numeric- only or alphabetic- only password (a mixture of both is best).
A strong password is necessary not just to protect your blog content. A hacker who gains access to your administrator account is able to install malicious scripts that can potentially compromise your entire server. In addition to using a strong password, it's a good idea to enable two- step authentication as an additional security measure. FTPWhen connecting to your web server you should always use SFTP encryption if your web host provides it. If you are unsure if your web host provides SFTP or not, just ask them. Using SFTP involves the same process as FTP, except your password and other data is encrypted as it is transmitted between your computer and your website.
This means your password is never sent in the clear and cannot be intercepted by an attacker. Most FTP clients support SFTP. File Permissions.
Some neat features of Word. Press come from allowing various files to be writable by the web server.
However, allowing write access to your files is potentially dangerous, particularly in a shared hosting environment. It is best to lock down your file permissions as much as possible and to loosen those restrictions on the occasions that you need to allow write access, or to create specific folders with less restrictions for the purpose of doing things like uploading files. Here is one possible permission scheme. All files should be owned by your user account, and should be writable by you.
Any file that needs write access from Word. Press should be writable by the web server, if your hosting set up requires it, that may mean those files need to be group- owned by the user account used by the web server process. The root Word. Press directory: all files should be writable only by your user account, except . Word. Press to automatically generate rewrite rules for you. The Word. Press administration area: all files should be writable only by your user account. The bulk of Word.
Press application logic: all files should be writable only by your user account. User- supplied content: intended to be writable by your user account and the web server process.
Within /wp- content/ you will find. Theme files. If you want to use the built- in theme editor, all files need to be writable by the web server process. If you do not want to use the built- in theme editor, all files can be writable only by your user account. Plugin files: all files should be writable only by your user account.
Securing Your Lync Server (Part 1)If you would like to read the other parts in this article series please go to: Introduction. Today's business world is all about communications, and many enterprises use Microsoft's Lync unified communications platform for instant messaging, voice and video conferencing. Microsoft has built additional security features into the latest version of Lync, and as with any software, how you configure and use it plays a big part in security.
In this article, we'll look at what Lync is and how it works, the security mechanisms that are included and how you can best secure your organization's Lync server. The evolution of Lync. Microsoft Lync is the renamed and “reimagined” iteration of the enterprise software formerly known as Office Communications Server (OCS), which itself got its start back in the heyday of Microsoft’s “live” period, as Live Communications Server 2. It was renamed to OCS in 2. Lync in 2. 01. 0. Prior to the release of LCS, Microsoft included instant messaging functionality in Exchange 2.
LCS and removed it from Exchange 2. The current version is Lync Server 2. October 2. 01. 2. It has grown to include not just instant messaging and file transfer but also presence (indication of availability status), Voice over IP (Vo.
IP), and audio and video conferencing, with others within the local network, external users over the Internet and over traditional PSTN phone lines via a SIP gateway or trunk. Participants in a Lync collaboration session can also share desktops, applications, One. Note notes, documents, presentations, whiteboard drawings, and polls. Organizers of Lync conferences can designate whether particular participants are attendees only or presenters and set policies and permissions governing what participants in each category can do. You can also organize topic- based virtual chat rooms for working groups.
How it works. Although it’s now a separate product, Lync integrates with Exchange server and retrieves contact information from the Exchange database. Lync uses the SIP (Session Initiation Protocol) protocol, which is a standard for Internet voice and video, for communications with the client software and SIMPLE extensions (SIP for Instant Messaging and Presence Leveraging Extensions) are used for managing presence information and short real- time messages. RTP (the Real- time Transport Protocol) and SRTP (Secure RTP) are used to transfer media. Communications can also be encrypted by using SIP over TLS (Transport Layer Security).
Lync client software is available for Windows PCs and Mac OS X. There is a Lync app in the Windows Store for Windows 8/8.
RT, a “Basic” client that doesn’t support multi- party video, VDI, One. Note integration, advanced call handling and some other features. Those features are included in the full Lync 2.
Users who can’t or don’t want to install the Lync software on their computers can use the Lync Web App. There are also versions available from Microsoft for Windows Phone 7 and 8, Android and i. OS devices. There is a Lync client for Linux made by Fisil, a company that provides Lync software and outsourcing services. You can see the differences between the functionalities of different clients in the Client Comparison Tables on the Tech. Net web site. Lync security mechanisms. Lync uses your organization’s PKI (public key infrastructure) or a public CA (certification authority) to issue certificates for the private keys and session keys that are used to encrypt and decrypt information that’s sent over TLS connections, which helps prevent man- in- the- middle attacks and eavesdropping. The Lync server requires that certificates meet its specifications; not all public CAs do so.
The CA must be trusted by the client and the server’s DNS name has to match that on the certificate. MTLS (Mutual TLS) is used for protecting server- to- server communications. Instant messages sent over Lync can be encrypted via TLS and MTLS, both internally and over the Internet. Internal messages ca be sent over TCP (unencrypted) but best security practice is to use TLS. Shared desktop and web conferencing are also protected by TLS, while sharing of audio and video media are protected by SRTP and downloading of address books and meeting content is protected by HTTPS.
User authentication is accomplished via either Kerberos v. NTLM if the user has Active Directory credentials. Kerberos is used for users on the internal network and NTLM is used when users connect from outside the internal network. Kerberos can be used for external users if they connect through a VPN. Anonymous users (those with no Active Directory credentials) are authenticated via Digest protocol. Users can also be authenticated by client certificates issued by the Lync server. These certificates can’t be issued by the PKI or a public CA, only by the Lync server.
Active Directory and Group Policy. Lync stores global settings, service information about the servers running Lync and some user settings in the Active Directory database.
Lync 2. 01. 3 client group policies are now included in the Office Group Policy Administrative Template, instead of having a standalone administrative template as previous versions of Lync and Office Communicator had. You can also use a third party product such as Policy. Pak to manage the Lync 2. The ADMX (administrative template) file that you use to apply Group Policy that controls the client bootstrapping settings (settings that are needed before the client logs onto the Lync server) is called Lync. It’s part of the Office 2. You’ll need to download the 3.
Office 2. 01. 3/Lync 2. It’s an executable file, for example admintemplates_3. After you run the . In the spreadsheet, you’ll find a list of settings for the GPO. You can filter the file name column to display Lync. You’ll find this file in the admx folder. You can put the admx file in a central store (for use of multiple administrators) or you can put them on a computer running Windows 7 or 8/8.
If you create a central store, you will put each language specific template into a separate folder within a root folder and the non- language specific templates in the root folder. Create the folder on the domain controller operating as PDC emulator and it will replicate to your other DCs. Details for creating a central store, as well as the instructions for installing the administrative templates on a workstation, can be found on Daniel Petri’s web site at http: //www. Lync Server Management Shell and Lync Server Control Panel.
For those who prefer to perform admin tasks via a graphical interface, Lync Server 2. Lync Server Control Panel that is automatically installed on Lync servers and can also be installed on another computer for centrally managing Lync servers. IT admins who have kept abreast of what’s going on with Microsoft server operating systems know that the company has gone back to “the dark place” – the command line – in a big way. Power. Shell is the preferred management interface now, and most of the settings for Lync 2. Power. Shell, using the Lync Server Management Shell.
The Lync Server Management Shell is already installed when you install Lync Server (Enterprise Edition Front End Server or Standard Edition). You must use it to run the Lync Server cmdlets; you cannot run these in the regular Windows Power. Shell interface. There are over 5. Lync Server 2. 01. You can get a list of all of the Lync Server 2. Lync Server Management Shell: Get- Command * - Module Lync - Command. Type cmdlet. There are many different kinds of cmdlets.
There are 5. 4 cmdlets that are classified as security related, which include cmdlets for managing certificates and authentication, user rights and permissions, and interoperability. Many of the cmdlets are used for delegating administrative control of the Lync Server using the new role- based access control feature (RBAC).
There are a number of administrative roles already included in Lync Server 2. There is an Active Directory group created for each of the roles. When you create your own roles, you must first create the corresponding AD universal security groups. The highest level role is Cs. Administrator, which can perform all administrative tasks, including creating new roles.
Other built- in roles include: Cs. User. Administrator. Cs. Voice. Administrator. Cs. Server. Administrator. Cs. View. Only. Administrator. Cs. Help. Desk. Cs.
Archiving. Administrator. Cs. Response. Group. Administrator. Cs. Response. Group. Manager. Cs. Location. Administrator. Cs. Persistent. Chat.
Administrator. The scope of each role’s authority is in most cases indicated by the name. For example, the Cs. Voice. Administrator can only create, configure and manage voice- related settings and policies. The RBAC limitations only apply when a user is managing the Lync Server remotely, not when physically working on a local server. Summary. In this, Part 1 of this series on securing your Lync server, we took a look at what Microsoft Lync is, how it works, and the security mechanisms and management tools that are built in.
In Part 2, we’ll get into some of the details of how to harden and protect your Lync server and the Lync database, and how to plan and configure two- factor authentication for Lync. If you would like to read the other parts in this article series please go to.
