  • Getting Internet Explorer to Open Different Sets of Tabs Based on the Day of the Week

    - by Akemi Iwaya
    If you have to use Internet Explorer for work and need to open a different set of work-specific tabs every day, is there a quick and easy way to do it instead of opening each one individually? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader bobSmith1432 is looking for a quick and easy way to open different daily sets of tabs in Internet Explorer for his work: When I open Internet Explorer on different days of the week, I want different tabs to be opened automatically. I have to run different reports for work each day of the week and it takes a lot of time to open the 5-10 tabs I use to run the reports. It would be a lot faster if, when I open Internet Explorer, the tabs I needed would automatically load and be ready. Is there a way to open 5-10 different tabs in Internet Explorer depending on the day of the week? Example: Monday – 6 Accounting Pages Tuesday – 7 Billing Pages Wednesday – 5 HR Pages Thursday – 10 Schedule Pages Friday – 8 Work Summary/Order Pages Is there an easier way for Bob to get all those tabs to load and be ready to go each day instead of opening them individually every time? The Answer SuperUser contributor Julian Knight has a simple, non-script solution for us: Rather than trying the brute force method, how about a work around? Open up each set of tabs either in different windows, or one set at a time, and save all tabs to bookmark folders. Put the folders on the bookmark toolbar for ease of access. Each day, right-click on the appropriate folder and click on ‘Open in tab group’ to open all the tabs. You could put all the day folders into a top-level folder to save space if you want, but at the expense of an extra click to get to them. If you really must go further, you need to write a program or script to drive Internet Explorer. The easiest way is probably writing a PowerShell script. Special Note: There are various scripts shared on the discussion page as well, so the solution shown above is just one possibility out of many. If you love the idea of using scripts for a function like this, then make sure to browse on over to the discussion page to see the various ones SuperUser members have shared! Have something to add to the explanation? Sound off in the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.

  • How do I use Group Policy on a domain to delete Temporary Internet Files?

    - by Muhammad Ali
    I have a domain controller running on Windows 2008 Server R2 and users login to application servers on which Windows 2003 Server SP2 is installed. I have applied a Group Policy to clean temporary internet files on exit i.e to delete all temporary internet files when users close the browser. But the group policy doesn't seem to work as user profile size keeps on increasing and the major space is occupied by temporary internet files therefore increasing the disk usage. How can i enforce automatic deletion of temporary internet files?

  • LAMP stack security question - uploading files to server

    - by morpheous
    I am running Ubuntu 9.10 desktop on my home machine. I need to upload files from my local machine, to my web server, on a periodic basis. My server is running Ubuntu Server LTS. I want my server to be secure, and only run the LAMP stack and possibly, an email server. I do not (ideally) want to have FTP or anything that can allow (more) knowledgeable hackers to be able to hack into my server. Can anyone recommend how I may send files from my local machine to the server? This may seem an easy/trivial question, but I am relatively new to Linux - and I got my previous Windows server machine serious hacked in the past, hence the move to Linux, and thats why I am so security conscious.

  • Security Essentials not installing and I suspect my machine is infected with malware

    - by Jim
    My mouse seems to be automatically right-clicking every few seconds, and sometimes constantly. My cursor will abruptly become an hourglass for a moment every once in a while, as well. It happens in spurts, as in it hasn't happened for about 10 minutes, but the preceding 20 before that it was happening constantly. I suspect that my machine is infected with malware of some sort, so I've tried installing Microsoft Security Essentials, but it presents the following error upon installation failure: My questions are: How can I solve the MSE installation issue and run a scan? Are there any indications that malware isn't actually my issue? Is MSE my best way to go about solving my issue, assuming that malware actually is the problem? Many thanks!

  • Would Microsoft Security Essentials be adequate protection?

    - by Xavierjazz
    Is Microsoft Security Essentials (MSE) adequate protection for my computer? What is the experience with this product? EDIT. On 2009-10-31 I found out about a comparison of AV Suites. MSE did VERY well. EDIT: One that I found interesting was "Raven", who mentioned that AV software has to hook deeply into the OS, and who better to design this than the designer of the OS. EDIT: My personal experience is that I like it, but I also use Malwarebytes and Superantispyware. Each of them sometimes come up with one the others missed or ignored.

  • Windows 7: Open File - Security Warning box appears for every app on the desktop

    - by Michael Ratanapintha
    Whenever I double-click to open an executable on the desktop (.exe, .bat, etc.), or a shortcut on the desktop that points to an executable, the "Security Warning" pops up and asks me "Are you really sure you want to open that? Stuff from the Internet is dangerous!" I don't usually mind this warning and don't want to disable it globally, but now I'm getting it for any executable on the desktop, even ones that I didn't download from the Web and don't have the Mark of the Web alternate data stream. (That is, streams -d * shouldn't and doesn't help.) This started fairly recently, but I can't really point to anything I did that triggered it. It only occurs in one user account on the machine; the other account doesn't have this problem. Running System Restore didn't help. How can I fix the problem and make the pop-up warning appear only when it's supposed to?

  • Security in OBIEE 11g, Part 2

    - by Rob Reynolds
    Continuing the series on OBIEE 11g, our guest blogger this week is Pravin Janardanam. Here is Part 2 of his overview of Security in OBIEE 11g. OBIEE 11g Security Overview, Part 2 by Pravin Janardanam In my previous blog on Security, I discussed the OBIEE 11g changes regarding Authentication mechanism, RPD protection and encryption. This blog will include a discussion about OBIEE 11g Authorization and other Security aspects. Authorization: Authorization in 10g was achieved using a combination of Users, Groups and association of privileges and object permissions to users and Groups. Two keys changes to Authorization in OBIEE 11g are: Application Roles Policies / Permission Groups Application Roles are introduced in OBIEE 11g. An application role is specific to the application. They can be mapped to other application roles defined in the same application scope and also to enterprise users or groups, and they are used in authorization decisions. Application roles in 11g take the place of Groups in 10g within OBIEE application. In OBIEE 10g, any changes to corporate LDAP groups require a corresponding change to Groups and their permission assignment. In OBIEE 11g, Application roles provide insulation between permission definitions and corporate LDAP Groups. Permissions are defined at Application Role level and changes to LDAP groups just require a reassignment of the Group to the Application Roles. Permissions and privileges are assigned to Application Roles and users in OBIEE 11g compared to Groups and Users in 10g. The diagram below shows the relationship between users, groups and application roles. Note that the Groups shown in the diagram refer to LDAP Groups (WebLogic Groups by default) and not OBIEE application Groups. The following screenshot compares the permission windows from Admin tool in 10g vs 11g. Note that the Groups in the OBIEE 10g are replaced with Application Roles in OBIEE 11g. The same is applicable to OBIEE web catalog objects.    The default Application Roles available after OBIEE 11g installation are BIAdministrator, BISystem, BIConsumer and BIAuthor. Application policies are the authorization policies that an application relies upon for controlling access to its resources. An Application Role is defined by the Application Policy. The following screenshot shows the policies defined for BIAdministrator and BISystem Roles. Note that the permission for impersonation is granted to BISystem Role. In OBIEE 10g, the permission to manage repositories and Impersonation were assigned to “Administrators” group with no control to separate these permissions in the Administrators group. Hence user “Administrator” also had the permission to impersonate. In OBI11g, BIAdministrator does not have the permission to impersonate. This gives more flexibility to have multiple users perform different administrative functions. Application Roles, Policies, association of Policies to application roles and association of users and groups to application roles are managed using Fusion Middleware Enterprise Manager (FMW EM). They reside in the policy store, identified by the system-jazn-data.xml file. The screenshots below show where they are created and managed in FMW EM. The following screenshot shows the assignment of WebLogic Groups to Application Roles. The following screenshot shows the assignment of Permissions to Application Roles (Application Policies). Note: Object level permission association to Applications Roles resides in the RPD for repository objects. Permissions and Privilege for web catalog objects resides in the OBIEE Web Catalog. Wherever Groups were used in the web catalog and RPD has been replaced with Application roles in OBIEE 11g. Following are the tools used in OBIEE 11g Security Administration: ·       Users and Groups are managed in Oracle WebLogic Administration console (by default). If WebLogic is integrated with other LDAP products, then Users and Groups needs to managed using the interface provide by the respective LDAP vendor – New in OBIEE 11g ·       Application Roles and Application Policies are managed in Oracle Enterprise Manager - Fusion Middleware Control – New in OBIEE 11g ·       Repository object permissions are managed in OBIEE Administration tool – Same as 10g but the assignment is to Application Roles instead of Groups ·       Presentation Services Catalog Permissions and Privileges are managed in OBI Application administration page - Same as 10g but the assignment is to Application Roles instead of Groups Credential Store: Credential Store is a single consolidated service provider to store and manage the application credentials securely. The credential store contains credentials that either user supplied or system generated. Credential store in OBIEE 10g is file based and is managed using cryptotools utility. In 11g, Credential store can be managed directly from the FMW Enterprise Manager and is stored in cwallet.sso file. By default, the Credential Store stores password for deployed RPDs, BI Publisher data sources and BISystem user. In addition, Credential store can be LDAP based but only Oracle Internet Directory is supported right now. As you can see OBIEE security is integrated with Oracle Fusion Middleware security architecture. This provides a common security framework for all components of Business Intelligence and Fusion Middleware applications.

  • What’s New In Microsoft Security Essentials 2.0 And How To Upgrade To 2.0

    - by Gopinath
    Since Microsoft released Microsoft Security Essentials(MSE) couple of years ago, I stopped worrying about antivirus programs on all my Windows PCs. MSE is just awesome and it’s the best free antivirus available in the market. Microsoft released version 2.0 of MSE yesterday with enhanced security features and more love for Windows users. New features introduced in this version are New protection engine - Heuristic scanning engine is introduced to bump the virus detection and cleaning mechanism. Network inspection system to monitor network traffic as we browse and protects us from malicious scripts and programs. Better integration with Windows Firewall With this upgrade, MSE is irresistible antivirus application to have on every Windows PC.

  • SQLAuthority News – 2 Security Updates for SQL Server 2000 SP 4 Users

    - by pinaldave
    If you are using SQL Server 2000 still today my very first recommendation to you is to upgrade to SQL Server 2012. SQL Server 2000 is now 12 years old product and since then many new enhancements as well features which are relevant to current growth and progress in Informational Industry. Now is the time to catch up with the latest trends. Here is one more point for you to notice if this helps you consider to upgrade to the latest version. One can’t upgrade directly from SQL Server 2000 to SQL Server 2012. You need to first upgrade to either SQL Server 2005/2008/R2 and then further plan to upgrade to SQL Server 2012. There is no direct upgrade path for SQL Server 2000 to SQL Server 2012. I strongly believe this is the time to upgrade to the latest version. Well, also there is a rule that to let something continue if it is not broken and working fine. If you are following that rule and still using SQL Server 2000 I strongly suggest that you upgrade your SQL Server 2000 SP4 and update it with latest Security updates. Here are two important SQL Server Security Updates. Security Update for SQL Server 2000 Service Pack 4 (KB983811) Security Update for SQL Server 2000 Service Pack 4 (KB983812) As we are talking about SQL Server 2000 let me ask you a quick question – how many of you are still using SQL Server 2000 or earlier version in a production system on at least one server?

  • Web security course ?

    - by vtortola
    I'd like to do a course about web security. I've seen some certifications that could be interesting: CIW Web Security Professional CISSP® - Certified Information Systems Security Professional Certified Secure Software Lifecycle Professional What do you know about these certifications? are they recognized? I'm not trying to become a hacker, I just want to ensure I have enough knowledge about web security to cope with today internet. From my inexpert point of view, "Certified Secure Software Lifecycle Professional" looks exactly as I want, the problem is that it cost more than 500 bucks! Why certification? well, I want to learn but I would like also have a way to demonstrate to a future employer/customer that I had to study and pass exams, not only attend to a course. Regards.

  • Security aspects of an ASP.NET that can be pointed out to the client

    - by Maxim V. Pavlov
    I need to write several passages of text in an offer to the client about the security layer in ASP.NET MVC web solution. I am aware of security that comes along with MVC 3 and an improvements in MVC 4. But all of them are non conceptual, except for AntiForgeryToken (AntiXSS) and built-in SQL Injection immunity (with a little of encoding needed by hand). What would be the main point of ASP.NET security I can "show off" in an offer to the client?

  • Open Source Security packages for Rails

    - by Edwin
    I'm currently creating a complete web application using Rails 3 to familiarize myself with its inner workings and to gain a better appreciation of a working web application's moving parts. (Plus, since I'm still working on my degree, I hope that it will give me a better idea of what's BS in my education requirements and which weaknesses/skills I should focus on.) The example application I'm working on is an ecommerce site, and I've already configured the backend, routes, controllers, and so on. As part of the application, I'd like to integrate a second layer of security on top of the one Rails already provides for user authentication. However, I've been unable to find any on Google, with the exception of OAuth - which, from my understanding, is meant to secure API calls. While I could roll my own secure authentication system, I'm only in my second year of college and recognize that A) I know little about security, and B) there are developers that know much more about security that are working on open-source projects. What are some actively developed open-source security packages or frameworks that can be easily added to Rails? Pros and cons are not necessary, as I can do the research myself. P.S. I'm not sure whether I posted this in the right SE site; please migrate to SO or Security if it is more appropriate there.
