  • How difficult is it to setup a mailserver?

    - by Jacob R
    I want a secure mail solution, as I am looking to move away from Google and other parties looking into my private data. How much of a PITA is it to setup my own mailserver? Should I go for an external provider with a good privacy policy and encrypted data instead? I have a VPS running Debian (with a dedicated IP + reverse DNS), and I'm a fairly capable Linux administrator, having setup a couple of webservers, home networks, and looking over the shoulder of sysadmins at work. The security I currently have on the VPS is limited to iptables and installing/running the bare minimum of what I need (currently basically irssi and lighttpd). When setting up a mail server, is there a lot of stuff to take into consideration? Will my outgoing mail be marked as spam on other servers if I don't implement a number of solutions? Will reliable spam filtering be difficult to setup? Can I easily encrypt the stored mail?

  • secure synchronization of large amount of data

    - by goncalopp
    I need to automatically mirror a large amount (terabytes) of files in two unix machines over a slow link (1 Mbps). This needs to be done frequently, but the data doesn't change too much (delta transmission doesn't saturate the link). The usual solution would be rsync, but there's an additional requirement: it's undesirable, from a security standpoint, that either the source or destination machines have (keyless) ssh keys to each other, or any kind of filesystem access. All communication between the two machines should thus be initialized (and mediated) through a third machine. I've asked a separate question about rsync in particular here. Are there other obvious solutions I'm missing?

  • Running .net application over a network

    - by Marlon
    Hello, I need some advice please. I need to enable a .Net application to run over a network share, the problem is that this will be on clients network shares and so the path will not be identical. I've had a quick look at ClickOnce and the publish options in VS2008 but it wants a specific network share location - and I'm assuming this location gets stored somewhere when it does its thing. At the moment the job is being done with a old VB6 application and so gets around all these security issues, but that application is poorly written and almost impossible to maintain so it really needs to go. Is it possible for the domain controller to be set up to allow this specific .Net application to execute? Any other options would be welcomed as I want to get this little application is very business critical. I aught to say that the client networks are schools, and thus are often quite locked down as are the client machines, so manually adding exceptions to each client machine is a big no no. Marlon

  • How dangerous can javascript be?

    - by CrazyJugglerDrummer
    I have recently started using noscript (in addition to ABP). It took a little while to get used to it and can occasionally require some clicking when visiting a new site to investigate why the site's not working and where I need to allow javascript from. Is the extra security worth it? Some of the controversy is discussed here. I suppose it boils down to a matter of whether javascript is a genuine threat to your computer or not. Any thoughts on this?

  • How to force WinXP to ask for password before software installation/uninstall?

    - by crosenblum
    I really like some of the linux security measures it uses. So what i'd like to do is have WinXP Pro SP3 ask for my user password everytime i try to install/remove software. I know I can't make windows be as secure as linux, but i'd love to adopt some of the great ideas and measures used, as possible, to make windows more secure. Any suggestions? P.S. Are there other people out there, who try to make their windows feel more linux like? Just curious.

  • Remove SID with ICACLS

    - by chris
    I am trying to remove an obsolete SID (the account was apparently deleted). I've tried to run the following on the server (win2003) and a client (win7): icacls c:\path /remove *S-1-5-21-1883347182-1220252494-433279356-1095 /T But I always get the output Successfully processed 0 files; Failed processing 0 files without it doing anything. How can I get it to work? Update: I've used AccessEnum to get the SID because icacls only says "No mapping between account names and security IDs was done." but doesn't show the sid. The output from AccessEnum is: "Path" "Read" "Write" "Deny" "c:\path" "Administrators, S-1-5-21-1883347182-1220252494-433279356-1095, ..." "Administrators, S-1-5-21-1883347182-1220252494-433279356-1095, ..." ""

  • Does removing admin rights really mitigate 90% of Critical Windows 7 vulnerabilities found to date?

    - by Jordan Weinstein
    Beyondtrust.com published a report, somewhat recently, claiming among other quite compelling things, "90% of Critical Microsoft Windows 7 Vulnerabilities are Mitigated by Eliminating Admin Rights" Other interesting 'facts' they provide say that these are also mitigated by NOT running as a local admin: 100% of Microsoft Office vulnerabilities reported in 2009 94% of Internet Explorer and 100% of IE 8 vulnerabilities reported in 2009 BUT, reading the first page or so of the report I saw this line: A vulnerability is considered mitigated by removing administrator rights if the following sentence is located in the Security Bulletin’s Mitigating Factors section, ?Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. could be sounds pretty weak to me so and I wondered how valid all this really is. I'm NOT trying to say it's not safer to run without admin rights, I think that is well known. I just wonder if these stats are something you would use as ammo in an argument, or use to sell a change like that (removing users as local admins) to business side? Thoughts? Link to the report (pdf) [should this supposed to be a community wiki?]

  • Unexpected Access Denied error while accessing EFS encrypted file

    - by pozi
    I am getting Access Denied error when I try to access some files. ACL is OK, all ACE's all intherited, I have full access to these files and I am the owner of these files. ACE's are exactly same as other files in the same directory which are accessible without problems (doublechecked through Security Tab on file properties and cacls command). Files are EFS encrypted, however I should have access to these files, because they were encrypted by the same user account I am trying to access (decrypt) them. EFS settings are exactly same as other files in the same directory which are also encrypted and accessible without problems (doublechecked through cipher command and efsdump command (SysInternals)). In ProcMon utility (SysInternals) I am getting Access Denied entry while accessing these files. Files are not used (locked), checked by Unlocker utility. Up to now, I tought I understand NTFS ACL's and EFS mechanisms fairly well, but now I am completely stuck and I do not know how to access these files. Any thoughts?

  • Can I run a web site from my home network without jeapordizing other computers on my LAN?

    - by Alchemical
    I have a home LAN with 5 computers and a NAS, all connected to a Linksys router which is connected to my Cox cable modem. I'm interested in having one of my computers run an IIS-based web site and to have it be accessible to the internet with a static IP. However, I do not want o jeapordize the safety of the other computers on my home network! Is there anyway to do this safely, or as safe as possible? I may also like to run an FTP server from this computer. Finally, optionally I would like to allow remote access to this computer from the internet--but it seems to me that that may increase the security risk to the other computers substantially.

  • Which smartphone OS would you choose for your users ?

    - by Florent
    While we currently only use windows mobile smartphone, my boss seems less and less reluctant to try and choose a new kind of OS for our users corporate phones. For some reasons, we can't use a Blackberry Enterprise Server, so i guess our only choice is between Iphone OS and Android (or Blackberry without BES ? I don't really know if this works fine) We need activesync capable smartphones of course, and activesync security policies must be available (pin when using your phone for example). Centralized Phone management would be nice too :D Any ideas on what should be the best smartphone to choose for our users ?

  • On an unencrypted public wi-fi hotspot, what exactly is a packet sniffer doing to get another computer's packet?

    - by hal10001
    I get mixed results when reading information security articles, some of them stating that in order to do something similar you need to also setup some sort of honeypot with a running access point and local Web server to intercept traffic. Then other articles seem to indicate you don't need that, and you can just run Wireshark, and it will detect all packets being sent on the network. How could that be, and what exactly is a packet sniffer doing to get those packets? Does this involve intercepting wireless signals transmitted over the wireless protocol and frequency via the NIC on the computer running a program like Wireshark?

  • Where can I learn various hacking techniques on the web?

    - by Carson Myers
    I would like to try my hand at hacking -- that is, exploiting various website vulnerabilities. Not for any illegal purpose mind you, but so I can have a better understanding and appreciation of these exploits while writing my own web software. I seem to recall that there was a community that hosted a bunch of demo websites, and you had to find and exploit certain vulnerabilities with each one. I can't remember what it is called but this is the sort of thing I am looking for -- I have read a tonne of little XSS and CSRF examples but have yet to find a real-life hands-on example of one. Does anyone know of such a place, where I can be given an example page and look for security holes? I would really rather not try this with actual websites, I don't want to break any laws.

  • How can I secure Postgres for remote access when not in a private network?

    - by orokusaki
    I have a database server on a VMWare VM (Ubuntu 12.04.1 LTS server), and it just occurred to me that the server is accessible via the web, since the same physical server contains a VM that hosts public websites. My iptables in the database are such that only SSH traffic, loopback traffic, and TCP on port 5432 are allowed. I will only allow host access to the Postgres server from the IP of the other VM on the same physical machine. Does this seem sufficient for security, assuming there aren't gaping holes in my general OS configuration, or is Postgres one of those services that should never be web facing, (assuming there are some of "those"). Will I need to use hostssl instead of host in my pg_hba.conf, even though the data will travel only on my own network, presumably?

  • How to setup a user account for a web application

    - by ximus
    Hi, What are the main guidelines to setting up a user account on a Linux machine for a web app? In my case it is a Rails application that does file management. First thing I can think of is to limit access rights to only the directories it needs. But how exactly should I go about this? Setup rights through a user group or a through the user's ownership of those directories. I have very little experience in user rights management. What else do I need to consider? I've heard of ACL's and SELinux, do I need to look into any of these to guaranty decent security for my simple web app? Any advice about this and anything not mentioned welcomed, Thanks, Max. I will be using Ubuntu.

  • How to unblock chm files - unblock button is missing

    - by Yoav
    I downloaded a CHM file. When I double click it it prompts me to open / save / cancel. Whether I open or save a new copy, the 'new' version will prompt the same open / save / cancel popup ad infinitum. Searching google it seems that Microsoft have deemed it right for security reason to block these files by default. The solution is to right click the file, and click the 'unblock' button at the bottom: The problem is that I don't have that button on my system: BTW, the button is also missing for .exe files.I'm using Win7 64bit. Any ideas?

  • How to keep Windows 7 from sleeping while scanning the PC.

    - by D Connors
    So, I've been using Microsoft Security Essentials lately. And it usually takes a couple hours or more for it to full scan my hard drive. Because of that, I commonly leave it scanning while I go do something else. Problem is: 10 minutes later, windows 7 goes to sleep, and the scan is (obviously) paused. That's What I'd like to stop happening. So far, the only way I've been able to avoid it was to create a power plan, and switch to it while away, to keep the PC from sleeping. Problem is that I have to keep switching power plans and I'd like the PC to be able to go to sleep in case MSE finishes scanning and I'm still not back. Maybe I'm just asking for too much, but I've been surprised by the users here plenty of times already. So let me know if you know how to keep the PC from sleeping while MSE is scanning. Thanks

  • Apache server doesn't create directory or file under www-data user [duplicate]

    - by Harkonnen
    This question already has an answer here: What permissions should my website files/folders have on a Linux webserver? 4 answers very newbie to Apache here I installed Apache 2.4 on my Arch server where I installed newznab (a newsgroups indexer). I have noticed that all files newznab needs to create are created under my login user, and not apache default user (www-data). I read here that it's bad security practice to allow www-data to write files. I agree. But as an apache newbie, I would like to know where (in the httpd.conf I suppose ?) the user allowed to write files can be configured, because I want another account to be allowed to write files instead of my main account.

  • How important is patch management?

    - by James Hill
    Problem I'm trying to sell the idea of organizational patch/update management and antivirus management to my superiors. Thus far, my proposition has been met with two responses: We haven't had any issues yet (I would add that we know of) We just don't think it's that big of a risk. Question Are there any resources available that can help me sell this idea? I've been told that 55-85% of all security related issues can be resolved by proper anti-virus and patch/update management but the individual that told me couldn't substantiate the claim. Can it be substantiated? Additional Information 1/5 of our computers (the ones on the building) have Windows update turned on by default and anti-virus installed. 4/5 of our computers are outside corporate and the users currently have full control over anti-virus and Windows updates (I know this is an issue, one step at a time).

  • Configure Iptables to allow a PHP-app accessing a port-nr

    - by Camran
    I have a php-application which connects to another app called Solr (database search engine). I can via this php app add/remove documents (records) from the Solr index. However, the Solr security is low, and anybody with the right port nr can access Solr and remove documents (records). I wonder, is it possible to ONLY allow my own php-app to have access to Solr somehow? Prefferably via Iptables. I am thinking I can only allow my own servers IP to that port, and it would solve my problem, because PHP is a server-side code. But I am not sure. About the Php-app: The website is a classifieds website, and when users wants to add or remove classifieds, they do so through a php app, which is this one. The app has a function which connects to solr and updates the database (index). I appreciate detailed answers... Thanks

  • What is the best way to setup a public and private wireless access point on the same home network?

    - by Dougman
    For my home network (with internet provided from a cable modem) I would like to setup a secure wireless access point that I use for all of my personal connections (home PC, iPhone, Xbox, etc) and also another public access point that friends and folks in the neighborhood may connect to (for good karma). I want to ensure that my private traffic cannot be accessed from users of the public access point. I currently have one router that is running the Tomato firmware that I use with WPA security. What is the best way to accomplish this kind of setup securely (if it is possible in a home environment)?

  • Protecting Consolidated Data on Engineered Systems

    - by Steve Enevold
    In this time of reduced budgets and cost cutting measures in Federal, State and Local governments, the requirement to provide services continues to grow. Many agencies are looking at consolidating their infrastructure to reduce cost and meet budget goals. Oracle's engineered systems are ideal platforms for accomplishing these goals. These systems provide unparalleled performance that is ideal for running applications and databases that traditionally run on separate dedicated environments. However, putting multiple critical applications and databases in a single architecture makes security more critical. You are putting a concentrated set of sensitive data on a single system, making it a more tempting target.  The environments were previously separated by iron so now you need to provide assurance that one group, department, or application's information is not visible to other personnel or applications resident in the Exadata system. Administration of the environments requires formal separation of duties so an administrator of one application environment cannot view or negatively impact others. Also, these systems need to be in protected environments just like other critical production servers. They should be in a data center protected by physical controls, network firewalls, intrusion detection and prevention, etc Exadata also provides unique security benefits, including a reducing attack surface by minimizing packages and services to only those required. In addition to reducing the possible system areas someone may attempt to infiltrate, Exadata has the following features: 1.    Infiniband, which functions as a secure private backplane 2.    IPTables  to perform stateful packet inspection for all nodes               Cellwall implements firewall services on each cell using IPTables 3.    Hardware accelerated encryption for data at rest on storage cells Oracle is uniquely positioned to provide the security necessary for implementing Exadata because security has been a core focus since the company's beginning. In addition to the security capabilities inherent in Exadata, Oracle security products are all certified to run in an Exadata environment. Database Vault Oracle Database Vault helps organizations increase the security of existing applications and address regulatory mandates that call for separation-of-duties, least privilege and other preventive controls to ensure data integrity and data privacy. Oracle Database Vault proactively protects application data stored in the Oracle database from being accessed by privileged database users. A unique feature of Database Vault is the ability to segregate administrative tasks including when a command can be executed, or that the DBA can manage the health of the database and objects, but may not see the data Advanced Security  helps organizations comply with privacy and regulatory mandates by transparently encrypting all application data or specific sensitive columns, such as credit cards, social security numbers, or personally identifiable information (PII). By encrypting data at rest and whenever it leaves the database over the network or via backups, Oracle Advanced Security provides the most cost-effective solution for comprehensive data protection. Label Security  is a powerful and easy-to-use tool for classifying data and mediating access to data based on its classification. Designed to meet public-sector requirements for multi-level security and mandatory access control, Oracle Label Security provides a flexible framework that both government and commercial entities worldwide can use to manage access to data on a "need to know" basis in order to protect data privacy and achieve regulatory compliance  Data Masking reduces the threat of someone in the development org taking data that has been copied from production to the development environment for testing, upgrades, etc by irreversibly replacing the original sensitive data with fictitious data so that production data can be shared safely with IT developers or offshore business partners  Audit Vault and Database Firewall Oracle Audit Vault and Database Firewall serves as a critical detective and preventive control across multiple operating systems and database platforms to protect against the abuse of legitimate access to databases responsible for almost all data breaches and cyber attacks.  Consolidation, cost-savings, and performance can now be achieved without sacrificing security. The combination of built in protection and Oracle’s industry-leading data protection solutions make Exadata an ideal platform for Federal, State, and local governments and agencies.

  • Run Windows batch file on schedule as non-Administrator user

    - by Evgeny
    I'm running Windows XP x64 SP2. I have a Windows batch file that with some Robocopy commands that I want to run on schedule. I created a scheduled task for it, running as a dedicated user (not the user I'm logged on as), but it simply did not run. I could see successful logon events in the security log, so it got that far, but the commands in the batch file definitely weren't getting executed. After reading through all of http://social.technet.microsoft.com/Forums/en-US/winservermanager/thread/d47d116e-10b9-44f0-9a30-7406c86c2fbe/ I tried making the target user account an Administrator and that fixed it - the batch file ran just fine. Nothing else seemed to work. The thing is, I want it to run under a low-privileged account. Does anyone know how can I get a batch file to run on schedule as a non-Administrator?

  • Taking ownership of trustedinstaller files?

    - by P a u l
    vista32-sp1: I am unable to delete some files on my system that were installed with 'special permissions' by 'trustedinstaller'. I find the usual help suggestion to use 'takeown' is not working, all I get is access denied. I refuse to believe there isn't some way to delete these files, or that microsoft has finally acheived their perfect security filesystem. This is NOT a case of a file being locked by a process. If this is all it was, I could solve this by myself. I know there are some recommended unlocking programs and they might do some sort of file system trick, but I would like to know what my possible direct actions might be. If a 3rd party program can 'unlock' a file, I want to know the mechanism. But like I said 'takeown' at the command line is not working for this.

  • Why would you use EAP-TTLS instead of PEAP?

    - by Ivan Macek
    As I understood EAP-TTLS and PEAP share same level of security when implemented in wireless networks. Both only provide server side authentication via certificate. The drawback of EAP-TTLS can be non native support in Microsoft Windows so every user has to install additional software. The benefit of EAP-TTLS can be support for less secure authentication mechanisms (PAP, CHAP, MS-CHAP) but why would you need them in modern and properly secure wireless system? What are you opinions? Why should I implement EAP-TTLS instead of PEAP? Let's say that I have most Windows users, medium Linux users and least iOS, OSX users.
