Cisco Security :: Block Access To Some Websites On 887 Router?

Jul 11, 2011

I went through all discussions regarding how to block access to some web sites. And I was trying to implement them but it didn't work. I've used 887G-3G-K9 router and UC540, and I'm not sure if it's possible to do that on them or I need to get a license for that or to buy  ASA. How can I check that URL blocking is available feature on those devices?
 
I've used 2 methods:

1) ACL
 
2) class-map and policy-map
 
class-map match-any http
match protocol http url "*facebook.com*"
match protocol http url "*www.facebook.com*"

[Code]....

Security / Firewalls :: Block Software With Password Bypass?

Sep 2, 2011

I am currently running a Windows 2003 Server Edition and I have an issue, we run a small piece of software for controlling the nights takings which connects to the tills database on the network.This piece of software is not password protected and is held in a safe, however it has come to our attention that an employee may have taken possession of a copy of this application and we need to block the application been run on the network.Now this is were it gets difficult, I know to stop the application I could just use the Software Restriction Policy with Hash Rules which would solve that. However the problem is that sometimes people WILL need to run this software on the network and not get blocked.These people may not have their own accounts etc so I am trying to workout a way that we can allow someone to bypass the software restriction policy with a password prompt, is this possible or is their another way around this issue?

Security / Firewalls :: How To Block Websites From Viewing Personal Information

Mar 18, 2012

In my curiosity, when I typed one of my family members, I was so shocked to find that his personal information is right on the websites, as if he gave 'permission' to see his privacy, i.e., his age, marital status, even his home address. when I typed all of my family members, their personal informations are also on websites as if they all gave 'permission' to see their privacy.

It's 'privacy invasion' to see all of our family personal informations.

My question is; How to block websites from viewing all of my family members' personal informations?

Cisco Switching/Routing :: Enabling Port Security On C4507R Shuts Down Port

Aug 13, 2012

I'm trying to enable port security on several 4507R's. When I try to configure a range of ports the switch will randomly put 1 or 2 in err-disable.  It's different every time I apply the config to the same group of ports.  However if I do them one at a time it seems to work.  But I really don't want to configure 6 fully populated switches one port at a time.   We also have a lot of 3750's and they gave me no problem using a port range.

Windows 7 Machine - Block From WAN But Not LAN

Jun 29, 2011

I have a Windows 7 machine connected to my TV set. I want this machine to act as much as an appliance and as little as a PC as possible. To that end, I want it to be able to access my NAS disk, but not the Internet. Internet = annoying update messages (think Adobe), viruses, crap.I don't know if this is a setting that I can do in Win7 or in the DI-Link AirPlusG router thing

Cisco WAN :: 2960 - Block Outgoing Multicast On L2 Port?

Aug 2, 2012

is it possible to block outgonig multicast L2 frames on an Ethernet port in outgoing direction on a 2960 Switch?
 
I tried the "switchport block multicast" command, but the description of this feature relates to only "unknown" multicast!?
 
But what means "unknown multicast"? Even if activated, I see a lot of multicast traffic going out that port: IGMP, PIM, SSDP, HSRP, OSPF, .. and also pings and VLC streams to multicastaddresses (ip igmp snooping disabled).
 
I also tried to map a "mac access-list" to that port, but the "mac access-group" interface command is restricted to only incoming traffic.
 
Reason: we assume, that there are a couple of specific enddevices, that might react strange to some multicast. Therefor we would like to block outgoing multicast on that specific ports.
 
I tested it on a 2960 12.2(53)SE2

Cisco Firewall :: ASA 5510 - Setting Up SMTP Port Block?

Mar 5, 2012

how to go about setting up the ASA to block any SMTP traffic outbound except for our Exchange Server. This is in relationship to a SpamBot issue that blacklisted us. I have an ASA 5510 running version 6.2(5) / 8.2(2) with three ports. DMZ, Inside and the Outside interface. Up till today, I only needed to block outside traffic to our internal network which I used the ASDM to configure a rule on the outside interface for an incoming rule. I am assuming I need to create an outgoing rule on the outside interface; however, just to make sure I understand the terminology/traffic flow, I created the rule with my computer as the source (192.168.0.131) with ALL destination and the service as HTTP. My logic, which seems to fail here, is that any traffic from my computer going outbound would be blocked; however I am still able to browse... That said, if I were to change the source as the Exchange server and the Service Type to SMTP, it would not actually block traffic and therefore not solve our problem.  I even gone as far as permitting traffic from my computer, expanding the hit counter and I see no hits.  So I am no doubt doing this wrong. What I do know, is when I first created the rule, a second rule was automatically created (Implicit rule) that deny all sources and blocked all HTTP traffic until I changed it to Permit?

Cisco Firewall :: 5505 Block Port 80 On A Specific Host In LAN

Apr 22, 2012

I'm using an ASA5505 (8.4(1)) and would like to block port 80 on a specific host in the LAN so machines in other remote LANs connected via VPN can't access this port on the host. Devices in the local LAN should have access to this port on the host. Here are the commands I'm using:
 
-access-list block_port extended deny tcp any host 10.20.10.20 eq 80
-access-list block_port extended permit ip any any
-access-group block_port out interface inside
 
These commands are not working as I would expect them to. When I browse to http://10.20.10.20 from a remote machine over the VPN tunnel I am able to access the host web server.

Cisco Switching/Routing :: 3550 / Access List - Block One Ip Or Port

Jan 9, 2012

I have a layer 3 switch, 3550.I have several vlans on there just for playing around with. One of the vlans, has a vonage linksys box attached to it with a UK number attached. From time to time telemarketers call at 03:00 in the morning, this as I'm sure you can imagine is not much fun. The linksys box gets 192.168.3.3 as it's ip.The switch is connected to a non cisco router at 192.168.0.1
 
interface FastEthernet0/24
no switchport
ip address 192.168.0.2 255.255.255.0
 
I was thinking a time based access list would work best I have tried several variations but the phone still rings. I have tried access-list 1 deny host 192.168.3.3 permit ..... and more extensive lists but the phone still rings. I have not applied the time-range yet, so that's not the problem.I have applied the list to the vlan interface and to fa0/24 but it's not working.
