With the volume of malwares transferred through network increasing, network file inspection becomes more and more important. This feature will provide file type identification, file signature creation, and file capture capabilities to help user deal with those challenges.
There are two parts of file services: file APIs and file inspect preprocessor. File APIs provides all the file inspection functionalities, such as file type identification, file signature calculation, and file capture. File inspect preprocessor provides users ability to control file services, such as enable/disable/configure file type identification, file signature, or file capture.
At lease one of preprocessors supported protocols must be enabled.
< file_block_timeout timeout >: When a file transferred through HTTP is blocked , browser might resume file transfer with partial content in HTTP protocol. Snort block file even if it is transferred through resume. This timeout is to set how long it will keep blocking that file.
< file_capture_memcap memcap >: This sets the memory limit for file buffers, in megabytes.
< file_capture_max max >: Maximum file size we can capture. If file size is greater than this value file will not be captured.
< file_capture_min min >: Minimum file size we can capture. If file size is smaller than this value file will not be captured.
< file_capture_block_size size >: This sets the memory block size for file buffer. Smaller value might save memory but may hurt performance. Default is 32k bytes.
This set the file type depth 16K bytes, file signature depth 10M bytes, file block timeout 1 hour, file capture memcap 200M bytes, maximum file size to capture is 1M file, minimum file size to capture is 200 bytes, file block size is 64k.
< capture_memory >: Capture file to memory (file buffers). File analysis can be done on file buffers directly without the overhead of storing to disk.
< capture_disk dir >: Store files to the directory specified in dir, and capture no more than disk size (in megabytes). If this limit is reached, no more file capture.
< capture_network hostname portno >: Send files to other host, specified by hostname (or IP address) and port number.
< capture_queue_size size >: Set the maximum number of files can be queued to process (saved to disk or sent to network).
< blacklist file >: Specify a SHA256 list file. Files match SHA256 will be blocked.
< greylist file >: Specify a SHA256 list file. Files match SHA256 will be alerted.
SHA list file format one SHA per line. Use # for comments.
type: defines the name of file type. Name should be limited to any alphanumeric string including periods, dashes, and underscores.
id: used to uniquely identify different file types, similarly to rule ID.
ver: used to indicate different versions for the same file type.
category: defines the categories of file type. Name should be limited to any alphanumeric string including periods, dashes, and underscores. Categories can be Executables, PDF files, FLASH files, Office Documents, Archive, Graphics, Multimedia etc.
group: logical grouping of file rules, used for IPS rule keyword file_group. See README.file_ips for more information on 'file_group'.
msg: the message to print when file type information needs to be described.
content: defines the file magic using binary data. The binary data is enclosed within the pipe (|) character and represented as bytecode, i.e hexadecimal numbers.
offset: defines the location of file magic relative to the start of file.
rev: used to uniquely identify revisions of file type definition.
Similar to snort rule, it can be used through include directives. Similar file types can be put into the same file. Multiple file type configurations can be included in snort configuration.
The previous two rules define GIF format, because file magics are different.
Full set of file type magic rules are not included. Future release will include file type magic and rule options to use file type information.
File type events are generated when file type preprocessor rules are enabled. Each file magic rule requires one file type preprocessor rule. File type use 146 as generator ID.
File signature events are generated when file signature preprocessor rules are enabled. File signature use 147 as generator ID.
File services provide its own SHA calculations, but users can optionally enable openssl implementation. Openssl might provide performance optimization based on the platform snort runs. To enable it, the following options should be included in the ./configure command.
File capture relies on file type and file signature enabled. If file type is unknown, that file will not be captured. File signature is used as file ID to avoid downloading duplicated files.
All files captured will be saved to directory "tmp". File capture queue is set to 5000 files.
File inspect preprocessor provides a simple way to sending files to another host for further analysis. In tools/ directory, file_server is provided to receive and save all the files to disk.
All the files will be saved to the directory where the command is running.
File inspect preprocessor also works as a dynamic output plugins for file events. It logs basic information about file.


Edge Thanksgiving basket tracker 2018 – Who has the largest slice of the pie?
Sales of groceries online have more than trebled over the last five years and are predicted to quadruple in the next five (Packaged Facts). Amazon and Walmart remain the dominant players with a combined share of 28 percent of sales. However, smaller providers are also becoming more significant, most noticeably Instacart.
Instacart has recently announced new, and growing, relationships with some of the biggest retailers in the US. Aldi announced that it would roll out Instacart delivery to all of its stores nationwide and, after less than a year of working together, Instacart and Kroger announced that they would expand their delivery coverage by 50 percent.
There is also competition from other delivery firms such as Shipt, whose partners include Meijer and Target and supermarkets that deliver directly or pick up, such as Peapod, Fresh Direct, Safeway etc.
With Thanksgiving just a month away, retailers and delivery service providers will promote their online services heavily to help customers take the stress out of their Thanksgiving shop.
Edge has created a basket of popular Thanksgiving dinner items in five regions across the country. Due to the large variation in meat offerings in these retailers we have omitted turkey from this basket to allow a fair comparison. In the Los Angeles and Chicago we included alcohol in the basket, a bottle of wine and a six pack of beer, which was not possible in the other regions.
Because of the variation in regional offerings, the value of a basket in one region cannot be compared to another, as the basket will differ to some degree. We have looked at both the shelf price and promoted price to see the effect of bulk buy discounts on the value of the basket.
The effect of multi-buy discounts was most pronounced in Peapod where the effective value of its Brooklyn basket fell 6.5 percent and 6.9 percent in Chicago, making it the sole cheapest retailer in the Chicago comparison.
Food Town, Jewel-Osco, Marianos, Publix and Ralph's also employ multi-buy promotions., however, it did not change the ranking of the retailers.
The larger retailers showed the benefit of their economies of scale. Walmart was 25.8 percent cheaper than its nearest rival in Los Angeles, it had the sole lowest price on 18 of the 20 products in the basket. Walmart was also 18.2 percent cheaper than Publix in Atlanta, where it again was sole cheapest on all but two items in the basket.
Whilst bulk pricing discounts lowered the effective price of the basket, they may not be attractive to shoppers as they require a higher outlay to get the lower price.
For example, in Brooklyn, the price of a single can of 'Campbells Condensed Cream Of Mushroom 25% Less Sodium Soup 10.75oz' in Peapod was $2.19 for a single can the same price as Key Food but 15¢ higher than Food Town. However, the promoted price of this product is $1.64 but it requires the shopper to purchase 10 cans, a total minimum outlay of $16.40.
On the face of it the deal might not look that attractive, however, the deal extends to over 90 products across many brands and other Food Cupboard categories such as Canned Fruit, Canned Vegetables and Herbs & Spices. For those planning Thanksgiving dinner, this deal could appeal.
Food Town had a similar offer on 'Heinz HomeStyle Roasted Turkey Gravy 12oz' at 5 for $5. However, the deal only applied to other Heinz gravy products.
Thanksgiving is still 26 days away, so most retailers will have not started their promotional push for the holiday. Edge will be tracking this basket over the next month to see when the supermarkets launch their promotional campaigns and who has the most attractive prices.


Writing Belle: 300 Follower Giveaway!
I passed the 300 follower mark a long time ago, and since then I've had the fun of playing host to ARC giveaways, movie ticket giveaways and the like.

1. I can only ship to USA entrants. I'm sorry. But postage outside of the States costs more than the cost of one book!

That is not an easy question to answer. I'm going to say Forbidden by Tabitha Suzuma because that book was really emotional to me a really left a last impressing that I won't ever forget.

It seems I have a new favorite every other week LOL Often a new release to a favorite series will be released in the spring or summer so I will go with the Sookie Stackhouse series. They are just fun! Congratulations on this milestone and thank you so much for sharing your joy with us!
Aw! I want to say YES to all of them!! Alas... US only *pout* I really wouldn't want you to ship to Canada... you're right. The cost is ridiculous. Nevertheless... I WANT!! *sniffle* lol.
Oh gosh...I don't know. I just finished Wanderlove by Kierstin Hubbard and I loved it. The summer, beach, and love...what's not to adore!
This summer I've been reading Kristin Cashore's books, Graceling and Fire. LOVING them both! Can't wait to get to Bitterblue!
I don't know about all time, but this summer I have absolutely loved Slammed and Point of Retreat by Colleen Hoover. Simply amazing!

My favorite summer read of all time is probably The Summer series by Jenny Han. I fell absolutely in love with those books!
Sarah Dessen books are my favorite summer reads! I can't pick just one!!!

I don't know that I can pick an all time favorite, but this summer I have really enjoyed My Life Next Door by Huntley Fitzpatrick and an ARC of Renegade by J.A. Souders -- look for it this fall b/c it's awesome.
Of ALL time? I have to say Harry Potter!

The Truth About Forever is my favorite summer read as well!

I think my favorite summer read is a three-way tie right now between, Loving Summer by Kailin Gow, My Life Next Door by Huntley Fitzpatrick, and Pushing The Limits by Katie McGarry!

The Vampire Academy and Bloodlines series by Richelle Mead! They rocked.
My favorite Summer reads have been Sweet Evil and Obsidian. I just can't choose.

My favorite summer read would have to be either Divergent or Insurgent. Thanks for the giveaway!
