NOTE: There are some 120 pixels wide by 90 pixels high images that are used on this site as decorative button links that are really just thumbnail graphics that were made from screen shots of the actual page they are linked to. They do not have descriptions attached to them beyond what is included in their image and link attributes. If you want a larger rendition of those, simply click on them to go to the represented document.
This page is dedicated as the site's obligatory "descriptions.htm", which is meant to describe images for those readers who may not be able to view them. Most of the graphics used on this site are accompanied by a "d" link located at the bottom right of the image, as they may not have sufficient text that describes them adequately. When accessed, the "d" link will usually take you to an individual page which is dedicated to describe that image only. It is done in this manner because the amount of images on this site that require descriptions would create a very large "descriptions" page if they were listed cumulatively, and that would only cause additional problems for visitors with slower connections. A few images are left without these description links because they are deemed to have an adequate explanation through the textual content that is provided with them. If you have arrived here looking for descriptions of all the images used on site, it is hoped that the above alternatives will suffice.
The only exceptions to the above paragraph are this page and any future requirements for additional description pages. The latter will have links to them from here (which will be listed at the top of this page) as well as from the "d" link beside their respective images on their parent document, as is the case below the site's page header graphics description, which follows this text.
The graphics across the top of all pages of this site, except for the Text Version Entry Page described below, are otherwise identical and described here from the background to the foreground, and in the sequence that they occur from the left to the right. This 110 pixel high header layout is described with a screen size of 1024 by 768 pixels in mind, although the width will conform to any viewport size while the height remains fixed. The frame sets found on site may utilize a slightly customized array of these graphics. The theme is of light blue horizontal bands that stretch across the entire page on a white background. These bands fade out in a cumulative "C" shape on the left side which is inverted on the right side, to give somewhat of an elliptical impression that could represent the Internet. On the left side of all this, is a slightly darker blue representation of the Earth that emanates similar horizontal bands of it's own color to simulate a round aura that may constitute a fixed, but limited, DNS "zone" around the planet. This graphic seems to hover over the lighter blue bands which appear to refract with the darker ones, creating a sense of interaction between the two. A tiny green globe looks to be hanging in the orbit of the Earth to portray a fixed partnership within this interactive sea of Internet bands. Then, just left of center, there are the three "DNS and ICS" graphics; one for each of the three letter groupings. The Primary Navigation menu graphics are immediately below and centered to the very dark black-blue Niamey font lettering that was used for "DNS and ICS". They are a horizontal group of four white buttons, with a thin grey border around each. The names of the links are centered within them, in italic, dark blue Arial font, created with lower case typeset. These seven images will adjust their positioning dynamically if the viewport is adjusted in any direction, whereas the four images that make up the representation of the Earth and the Internet remain static in the background.
The page header graphics for the Text Version Entry Page are unique to the rest of this site, and are also described here from the background to the foreground, and in the sequence that they occur from the left to the right, with a screen size of 1024 by 768 pixels in mind and are positioned at the top center of that page.
The background image is a fixed, non-repeated transparent one called "d.gif" and it is 979 pixels in width and 87 pixels in height. There is a wispy, almost ethereal, purple, blue and turquoise "haze" effect (that the author refers to as "Etherhaze") which occupies the entire width of the graphic. It is dispersed as a broken cloud effect to create a semi-transparent background for this "background" image. Overlaid (from the left) are a series of 8 compasses that could represent the DNS system, then a blue spirograph which might represent the World Wide Web. There are no borders around this image, which is offered on a very lightly, tawny colored page.
The 8 compasses begin at the very farthest left, and vary in size and color ending with the largest of them, a blue "artist's rendition" of a compass on which the seven others are based. They each have 8 points, not unlike a star, on individual, circular shield-like disks. They become incrementally larger in a small sine wave, to appear as if they are coming out of the "Etherhaze", from a distance. Their individual color schemes are (from left to right) blue, green, gold, green, blue, green, gold, then end with the blue, and largest one, which is about 50 pixels by 50 pixels in size. The right-most point of the largest compass ends approximately 220 pixels from the left edge of the background graphic, and is barely overlaid onto the spirographical, net-like part of this image.
The spirograph is a blue, net-like collection of complimentary curves covering an area of 509 pixels wide by 64 pixels high, starting adjacent to the largest blue compass. It seems to "pour" out from the top area to the right of the largest blue compass, where it proceeds to extend across and down through it's area of the image in a flowing fashion, as if to present the site's name and navigation scheme to you. The curved, bright blue lines of the spirograph are thin and just noticeable enough to accent the horizontal navigation bar positioned in the center of the page. The "nav bar" and the remainder of the graphics that make up the page header layout are not part of the background image per se, and are positioned to appear to "float" over this background theme.
The horizontal navigation bar positioned in the center is made up of 5 white buttons, all of which are 120 pixels wide by 20 pixels high for each, and have dark blue, italicized Arial font in lower case that depicts their link names. These, and the other as-of-yet undescribed images that finish the page header graphics are designed to "float" dynamically across this background at any screen size, while maintaining a position directly over top of the aforementioned "fixed" background image. Each button link is separated by a 1 pixel by 1 pixel transparent spacer graphic placed between them.
Above the "nav bar" and overlaid on top of the spirograph, there are the three graphics responsible for the title images of the site. Each uses a progressively darker blue, italicized "Arial Black" font and these three are also closely centered to the layout so that they will appear to "float" above the navigation scheme. These too, grow incrementally larger from left to right to suggest a perception of depth, and they say (from left to right) "DNS", "and", then finally "ICS".
Additionally, and centered below the text content of the page, there is the Site Logo, logo1.gif, which is 74 by 63 pixels. Basically, the image has six gold "spokes" that emanate outward from it's epicenter which all have like-colored spheres of approximately 10 pixels in diameter attached to the ends of the thin spokes, except for the sphere at the end of the spoke that occupies the 10 o'clock position of this rounded shape. That spoke has an image of the Earth at it's end which is
about 30 pixels in diameter, noticeably larger than the golden spherical shapes of the other five. The "Earth" has blue oceans and green continents showing, with a hint at Polar Ice depicted near the top left of the planet. The six spokes, then, occupy even-numbered positions of a clock's hour hand. This logo is intended to represent the world we live in and it's correlation to Internet networking. This is also the original image used for the site's favicon.ico file that you may find in
your browser's Address bar when you visit here. The last time the page was edited will also show up in the alternative text when you hover your mouse cursor over the logo.
The above probably sounds a lot more grandiose than it actually looks, but it was a fun description as it is.

The images described below this text are from the ICS and the CHX-I Packet Filter page of this site and any addendum to this page will be reflected in a subsequent assertion similar to this one.
This is a black and white depiction of what an ICS network might look like in regards to a hardware setup. It shows the ICS computer connected to a cable modem, which is then connected to the Internet, which is displayed as an image of the earth encircled by a grey circle with the word "Internet" beside it. On the other side of the ICS computer are two more computers with a router (or hub) situated between all three. There are grey lines leading from the hub to all three computers. All five of these grey lines that connect between the devices signify two-way data cables for the ICS network.

This is a color depiction of the top left portion of CHX-I's Management Console which is cut and sized to display the sixteen filters or "rules" that are listed for the ICS Global Interface. The left 25% of the image is occupied by the first of two panes which displays the contents of the Tree tab. Starting from the top, the following are listed: CHX-I Management, which is expanded to show Services Status, Active Network Processes, Central Logs and Packet Filters (Global). Packet Filters
(Global) is further expanded here to show the two Interfaces used on the ICS machine, which usually show the MAC address for each. They have been cut out here for anonymity. The first is the LAN adapter, and the second is the ICS adapter we are interested in for now. Furthermore, two additional selections are listed for this branch and they are Inactive Filters and then Activated Hidden Filters.
The remaining 75% of the image to the right is the Description screen that lists the Description, Type, Action type and Direction of these sixteen filters or rules in columns. The rest of the screen to the right and below is cut-off in this graphic. The second column (Type) lists "Filter" for all sixteen entries. The fourth column (Direction) shows "Incoming" for all.

It is a group of graphics that comprise a clickable map of the world which displays an encyclopedic list of the Top 10 virii (including Trojans and Worms) at the top right area of the 300 pixels wide by 601 pixels high applet, as reported to Trend Micro. When an entry in the list is selected, you are directed to their site for more information regarding that particular scourge.
There are four drop-down menus that span across the top. They are titled "View By", "Track", "Select Map" and "Time Period". Each menu lists multiple choices to further define your query. When a continent is moused-over on this interactive object, the list changes to reflect the Top 10 virii for that region. If a continent is then mouse-clicked, a map of that region is retrieved and additional text boxes appear to list the virii that affect countries and regions shown on the new map. These may appear in various places, depending on the map selection, and replace the encyclopedic list of the Top 10 with the Top two. The drop-down menus then interact to further define these new text boxes.
All virus names listed in the applet are clickable, hypertext links that will take you from this site to Trend Micro's site, where you will find a description of the particular malware. Use your browser's Back function or your Backspace key to return to this page if you leave here, use the F5 key of your keyboard (may require clicking on an "open" text area of the page) or the browser's Refresh button to refresh the map after selecting a continent for more virus information. You can also refresh the applet by selecting "Location" from the "View By" menu or by selecting "Worldwide" from the "Select Map" menu.
