The WEB PAGE MONITOR service regularly checks that your web page is available and has not been defaced. 

Our defacement detection system is extremely sensitive. If a hacker changes a single character, WEB PAGE MONITOR will raise the alarm.

WEB PAGE MONITOR accesses your web page over the internet exactly as your customers do, so we can detect the failure of your web server, domain name server, internet connection or your ISP.

WEB PAGE MONITOR does not prevent your page being hacked - but we can warn you in time to minimize the damage. Secure systems, a culture of vigilance and contingency planning will reduce your exposure to intrusions - but no system can be guaranteed totally secure.

When it detects a problem, WEB PAGE MONITOR sends a message describing the problem to a set of email addresses specified by you. There is no limit to the number of addresses, and by using your mobile phone or paging company's email gateway, you and your staff can be immediately alerted wherever you are. When your site is back to normal, WEB PAGE MONITOR sends another message to let you know everything is OK.

For each alert address, you can choose normal or short alert messages. Normal alert messages provide a detailed analysis of the problem, including suggested action. Short alert messages are designed for delivery to pagers and phones.

• DEFACED: Your web site has been defaced or changed in some way. If it has been hacked, restore your original page - you should have backup copies readily available and a practised restoration process to minimise the outage. If WEB PAGE MONITOR has detected a valid change, log on to your control page and update the checksum. If there is no discernable change, view the source of your page - there may be differences inside tags that are causing false alarms. 
•  Necessary log on to WEB PAGE MONITOR and change the page address to the new location.

The WEB PAGE MONITOR service is built around a series of automated systems that we call monitor bots, which do exactly what your customers do - browse your web page.

However, there the similarity ends. A patrolbot is far more discerning than a human visitor - it will detect any change to the HTML on your web page, including the addition, deletion or modification of a single character. And a patrolbot is relentless - it will monitor your page like clockwork day and night every day of the week.

The patrolbots also time how long your web page takes to load each time they Monitor. If this exceeds the time you specified on your control page, you are alerted to the potential server crash, network outage or denial-of-service attack.

Once you have logged into your control page, you can update the reference checksum for any of your pages. You also have the option of halting monitors for each page.

So if you wanted to take your server down over a weekend to revamp your web site, you could stop monitoring on Friday evening, then start monitoring and update the reference checksum on Monday morning.

• Day and month names and abbreviations (like "Monday" and "Sep")
• All tag contents

A second solution is to wrap frequently changing sections in WEB PAGE MONITOR's special "ignore" tags, like this:

<!--ppi--> This is ignored <!--/ppi-->

Note that using ignore tags does introduce a small risk of undetected defacement, because a smart hacker could place his message in the ignored section. The tags are intentionally cryptic to reduce this threat. Also the ignore tags themselves are part of the MD5 checksum so a defacement inside ignore tags on a page that previously had none will be detected.

Yes - from your control page you can stop when WEB PAGE MONITOR will not monitor your site. So if you regularly take down your web server each day or each week, it is easy to prevent false alarms.

Because it is the focus of your site, hackers usually deface your home page. Automated worms like Code Red also attack your home page, but for a different reason - it is the only page they can be sure will exist.

So although we are glad to monitor  as many individual pages on your site as you want, we suggest that the home page for each site is the most important.

Many new customers find the web page they entered causes REDIRECT alerts. This happens because some webservers handle the translation from "www.yoursite.com" to "www.yoursite.com/index.html" by redirecting the browser. To check if this will affect you, type your address into your browser and see if it changes when you hit "Enter". If so, give WEB PAGE MONITOR the second (redirected) address.

Also please note that the patrolbots cannot process frames. They will only detect defacements of the main (frameset) page - to protect the frame contents you should give WEB PAGE MONITOR the direct address of the frame content page.

emailed automatically whenever your favorite Web pages change.

You can double-check the monitor  log with your server logs - each time a patrolbot visits your site, it leaves an entry in your server log.

You may also notice an effect on your web site's traffic statistics. If you choose five minute patrols for instance, you will receive 288 extra visits every day.

No problem - just click on the email us, type in your WEB PAGE MONITOR user ID or your email address. WEB PAGE MONITOR will search our database for your details, and if it finds them it will email you.

We take great care to ensure our systems are as secure as possible. However, we recognize that no system is 100% secure, and have designed WEB PAGE MONITOR so that even if our systems were completely penetrated, a hacker would find nothing that could compromise our customer's servers. Your login password is processed and stored as an MD5 hash, and all other information (page and email addresses etc.) is either public knowledge or relatively innocuous.

Every person and every organization is different, so it may be that our standard services are not what you need. Perhaps you need monitoring more frequently, a more complex escalation procedure, or voice alerts. Whatever your need, please contact us so we can tailor a solution just for you.
