A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.

WatchGuard’s new T15, T35 and T55 tabletop UTMs provide the highest-performing security inspection in their class, allowing users at small offices, home offices and distributed enterprises to experience blazing-fast Internet speeds without sacrificing enterprise-grade security.

What are the risks if MS NAC is installed in the AD/DC server (to save the cost of setting another
dedicated NAC server) & how can we mitigate this?

Was told NAC works by per L2 switch and not by per port?  Care to elaborate what my Network colleague said?

I got a spam from Cassi at Exact Data that claimed that Yahoo PPC ads are the next big thing. I didn't click anything, of course.
Having done Google for years, is there any truth in this claim?

Are Scammers sending any semi-plausible tech ads around to click-bait developers?
Is Adsense still the way to go for ads ?

Hi All,

can you please help me to know more about OS command injection and how to prevent it in asp.net web applications.

Many thanks

I encrypted a USB drive using BitLocker To Go in Windows 10 Pro and when I inserted it into a new machine it prompted for the password. Once I entered it in I noticed a More Options section which allowed me to check Automatically unlock on this PC. I have since realized I don't want this to occur but I don't know how to make it go back to the way it was. I looked in Credential Manager with no luck. Sorry I'm new to BitLocker.
Greetings PKI Experts,

I’m in a new position (have been with the company for almost four months).  I have been tasked to remediate various certificate related vulnerabilities at work.  This led me to start looking at our existing PKI structure.  To say that the existing PKI structure is less than ideal is putting it mildly.  Our existing structure is as follows:
•      We have an online root CA that has been installed on a server that is providing various other services to the network.
•      The root CA appears to be issuing certificates to new servers and workstations put on the domain.
•      We had a subordinate CA that was installed on a domain controller.  I believe the actual server with the ADCS installed on it crashed awhile back and the new domain controller (with the same name) never had ADCS installed on it.

Instead of trying to salvage the existing PKI environment, I have decided to setup a new PKI environment.  This is going to be my first production PKI deployment.  I’ve done it a couple of times in a lab environment, but I want to get this right.  The new environment will be setup as follows:
•      The root CA will be an offline root CA.  This will be a Windows Server 2012 R2 Datacenter server.
•      There will be an online subordinate CA.  This will aslo be a Windows Server 2012 R2 Datacenter server.
•      Possibly a web server where the root CA and subordinate CA will publish their CRLs, where the AIA will link to.

Here are some of the questions I have:
1.      Do I need to…
I was recently tasked with setting up a VPN for a client of ours for accessing files from home. We are able to successfully login however when we try to map drives or access resources we are unable to. Mapping drives errors as is we are not in that domain. Trying to access the drives through Explorer returns the same. Can anyone assist with this please?
in TrendMicro's  .dat file, I could issue  
  find/I "malware_name"  AVfile.dat
& it will list if a specific malware is found in it.

McAfee releases csv file (from its portal) the rulesets for various
vulnerabilities which I could search by CVE number.

I wanted to do the same with McAfee AV but from its  amcore.dat
is simply all binaries & won't return anything.  
Is there any method to check what malware/viruses it protects against
in the DAT?

A colleague told me McAfee don't permit its DAT file to be searched
& don't publish full list of malwares (not the new signatures updated)
for each DAT released, true?

Link below mention there's a way but when I login to McAfee portal,
don't see that option anywhere or I navigate wrongly:


Above link says:
 Try: http://www.mcafee.com/us/mcafee-labs/threat-intelligence.aspx
Select checkbox for 'Malware Name' and enter DNSChanger for the search.
Hello all,
I will be migrating a Watchguard XTM505 to a Watchguard M370.  I understand the step by step portion of the policy manager.
My question is that before I import the configuration file from the policy manager to the new M370 do I need to activate the new M370 or do anything else to it?

Im now at the nexpose scan but confused what and where this is configured.

I'm wondering how practical folks deal with "Penetration Testing" as compared with "Vulnerability Scanning".
I can run a Vulnerability Scan and, let's say, find no vulnerabilities.
But, I'm asked to run a Penetration Test in addition.
With no vulnerabilities to target, what's next?

As I understand it, the notion of a Penetration Test is to actively attempt to get information or deny service or ...., right?
So, if there are no known vulnerabilities, where does one begin to perform a Penetration Test of this sort?
Or, is a clean Vulnerability Scan considered to be "good enough"?

Your experience and thoughts please?  And, for a small organization, what affordable tools would you use?
My user cannot connect with Watchguard client or Shrewsoft client.  Switching users to myself I find that I cannot connect with Watchguard client but I can with Shrewsoft.  This is a Windows 7 Pro PC.  My windows 7 PC can use either client.  Why cant this user use the VPN?
I am trying to configure my Watchguard firewall [XTM 515 - Fireware 11.9.4] to allow certain machines access to the update site of a software provider. Unfortunately this software vendor does not hold the updates on systems that can be referenced via  fixed ip addresses but rely on referencing their infrastructure via a DNS name.  I don't seem to be able to setup a route using packet filters or proxies. Does anybody know of a way of doing this?
Ok further to an earlier post, I don't have the option to move out of IE & Adobe products (namely
Adobe Flash player, Acrobat/Reader,  Shockwave).

So I'll need specific hardenings & settings to make them more secure: attached is a draft I've got
but I'll need more such specific settings for Adobe Flash player, Java applets & Java Runtime
(I got a fair bit of Javascripts) & MS Office hardenings (& management of macros).

Much appreciated if anyone can add in some inputs on hardening/securing of these mobile codes.

Too much are intertwined that I can replace these Adobe products
Running a Nessus scan produces loads of results. Can anyone recommend a tool for building a coherent report that reasonably easy to use?
Hi experts,

This is a very weird thing. I think it is best I TRY to keep it simple, which is hard for me, and if you have questions, I can respond.

I have an eight computer client/domain network. We all use I.E. on Win 7. There are times I.E. has an issue with a certain site, so we have Firefox as well. (something I am considering getting rid of).

Two days ago, I was on my work computer and I was surfing important things with Yahoo (in other words -- good sites I hope). It was fine for an hour or so. I then had to go to Yahoo for a story. It was on it for about 30 seconds, when it instantly switched to the site below.


I am not used to Firefox requesting an upgrade like that and .js scared me a little. So, I simply closed the browser. A minute later, I got one of those popups telling you that a very nice person who monitors all Microsoft computers in the world simultaneously noticed I was infected and offered to help if I called him. Of course, I did not do this.

I ran MBAM and SAS and I have the MBAM endpoint product. I didn't find anything. Yes, I know that once infected, always suspected, but I really don't want to completely reformat this computer.

So, I did what any very intelligent, yet very stupid person would do. I tried to reproduce the problem I ran it once again, and it did the same thing so I closed the web browser. I then tried Chrome and I.E. in a VM on my pc and used Yahoo. Fine. I then used Firefox with Yahoo in the VM…
Our company utilizes Tenable Security Center for our vulnerability scanning, and BMC Client Management for our patching/mitigation.

What we are noticing, is that the 2 systems don't always "speak the same language".

For instance, Tenable might say that there is a vulnerability for Plugin ID 100551, but BMC doesn't look at the missing patch roll-up in the same manner.  Trying to reference CVE numbers and the like, also gets messy.

Is there some method in which we could readily compare missing patches between the 2 dissimilar systems?

Thank you
Why WDS says firewall if off when we have Comodo Internet Security Premium 10 (has Firewall)?  Also noticed "App & Browser control" says it's OFF and device may be vulnerable, what can be happening?

I'm in the process of setting up SSO for users so we can control our internet access. We only want domain users to access internet and none domain users such (visitors) need to be blocked.

I have read a couple of articles but am still a little unsure which method to use, so here I am asking experts for guidance. I would also appreciate if someone can write step-by-step setup guide or an article that I can follow with some screen prints?

Please also point out any "gotcha"

This article says that "Event Log Monitor” has to be installed on all domain controllers, but later its talks about pushing out SSO client to machines which is also used for authentication, so am a bit confused if this is needed or not? Please clarify

and then this video also talks about "Exchange Monitor" for authentication.. do I need all of these options or will one suffice?

much appreciated!

My colleague has managed to configure one of the PC as Super-Agent ie
other PCs could get the McaFee AV signature updates from it or

is this a 'push' update ie from Super Agent, it pushes to the slave PCs
or it's a pull ie Slave PCs pull signature updates from it?

How do we configure the slave PC portion (screen by screen will be good)?

Can anyone please tell me step by step how to stop a Watchguard XTM25 from blocking downloads of EXE files from a server hosted website (so need to add an exception as an IP address) .

Many thanks

All system in domain:

Our Nessus scans are indicating a vulnerability with the Product :
Microsoft Office 2016
  - C:\Windows\SysWOW64\mscomctl.ocx has not been patched.
    Remote version :
    Should be      :

There are two MSCOMCTL.OCX on the systems… one in the C:\PROGRAM FILES\MICROSOFT OFFICE\ROOT\VFS\SYSTEM folder which is the current version and the offending MSCOMCTL.OCX version found in C:\WINDOWS\SYSWOW64

My question is, is it safe to replace the offending MSCOMCTL.OCX with the newer OCX and if so what it the best way to do so?  I assumed I would need to unregister the OCX file, replace the old one with the new and run Regsvr32 on the newer OCX file.

PFA screenshot of found OCX files.


Has anyone run into this vulnerability and if so what was done to remediate the issue?  Many thanks in advance!
I need to look at a website. It is not a pentest itself. Just a vulnerability scan. What tools could I use to generate a complete report?
I also need to generate a less technical report.
Need more best practices & governance on mobile codes (eg: Flash player,
Pdf reader, JavaScript, Java Applets, ActiveX) as we have a few cases of
malicious codes being run when opening Pdf & 1 case of ransomware:

a) attachmt 1 is a screen of IE setting: mostly what to set in IE to stop ActiveX
    & to set to  Med-High (guess this is also to mitigate against ActiveX ?)

b) I wud say patch the various Adobe products (we use Adobe Flash &
     Shockwave) within 1 week upon release of patches ?

c) attachmt 2 has some suggestions on ActiveX & Java only: not much

d) Does AV mitigate against mobile codes vulnerabilities?  If so, keep
    AV signatures updated   is another mitigation

e) I'm sure IPS (NIDS & HIPS) have signatures for mobile codes but in
    McAfee's case, by default, they are rolled out in Detect & not Block
    mode?  Should they be in Block mode?

f) any other best practices & governances for mobile code?
