Enumeration Techniques - A research report

Introduction Extracting the names of user, machine, services and resources of network is defined to be enumeration. Environment of intranet would be the desired place for carrying out the techniques of enumeration. An active connection to systems and directed queries calls for the participation of enumeration. A data type comprising of a set of keyed out values such as elements, members or enumerators of the particular type in computer programming is referred to as enumeration type. A set of named integer constants lies in enumeration. The name of the enumeration tag is stated by the enumeration type and even the set of keyed out integer identifiers such as enumeration set, constants of enumerator or members are defined by it. One of the values of the enumeration set puts in the variable with enumeration type defined by that exceptional type. Expressions and operands of all arithmetic and relational operators could be indexed using the variables of enumeration type. By providing a substitute to the preprocessor directive of #define, enumeration gives out various advantages. The values can be generated for your use because of this advantage along with abiding scope of rules. In general values in an enumerated type are found to be different from each other and it could be compared and assigned with others. But the memory of computer, interpreters, and compilers don’t seem to have any particular concrete representation of enumeration type and they just represent them in an indiscriminate manner. In order to easily view a large amount of information about Active Directory objects in a single window a locally-written tool called Active Directory Enumerator is being utilized. By making use of active directory more than equipment could be brought off. Even the management of faculty and staff accounts could be managed to a limited extent. Certain fields related to active directory are based on data from the resources of human and the office of the registrar. Information about the user of Active Directory such as groups belonging to the server of exchange, final change of password, etc could be found out by enumerator in a single convenient interface of user. Even if the same enumerator is allowed twice by some languages in the declaration of types, they are found to be distinct in many cases. Information on system hacking cycle By using Win 2K enumeration and SNMP probing, user names are extracted and even the password of the user is cracked thereby gaining an access to the system. By incorporating these steps one could get to the level of an administrator and start planting loggers for key, root kits and spywares on the machine. In order to hide the tools and source code used for hacking, stenography could be used. By implementing this method one could easily erase the tracks and escape from being caught. [1] Intruders Enumerate Certain Type of Information More self-documenting code was created by enumerated types. The default values to the enumerators are automatically assigned by the compilers based upon the type of language. By that means they blot out unnecessary particulars from the programmer. Even the programmer could not view these values. Illogical code writing by a programmer such as executing mathematical operations on the values of the enumerators could also be precluded by the enumerated types. The name of the enumerator could also be printed by some programming languages instead of printing its underlying numerical value if that value of a variable was attributed as an enumerator that were to be printed. In a conceptual manner, since a distinctive natural number is assigned by each possible value of the type list of nominal is said to be standardized as enumerated type. Therefore imparted enumerated type is thus a concrete execution of this impression. Enumerated type becomes an ordinal type when order is significant. [1] Resources and Shares of Network In order to start out the enumeration of a container resource of a network, the following steps must be executed by your application: To enumerate the resource of a network, functions such as WNetOpenEnum( ) and WNetEnumResource( ) must be utilized by us. Since passing NULL calls back wield to the root of the network a NULL is authorized in the first call of WNetOpenEnum( ) function. As Resource-Global net is moved over to enumerate all the resources of the net, the first parameter of WNetOpenEnum( ) is found to be the range of the enumeration. The type of the resource such as disk or print to be enumerated is specified by the second parameter. The desire to enumerate the container as well as the resources of the connectable could be easily indicated by simply passing 0 as third parameter. The pointer to the structure of NETRESOURCE is meant to be the fourth parameter.The address of a variable HANDLE is the last parameter. The handle to the network resource in the variable HANDLE is set by the function WNetOpenEnum( ). Subsequently this handle is passed to WNetEnumResource( ) function. By making a call to this function, information about the resource is returned in the sort of a lay out of NETRESOURCE structures. The variable specifying number of entries to list is mentioned by the second parameter of WNetEnumResource( ) that acts as a pointer. The function coming back as many entries as possible is denoted by the 0xFFFFFFFF. Enumeration results are received by the third parameter that is the buffer. The size of the buffer determined in the third parameter is considered as last parameter. Most of the time, 16KB is tend to be the size. The list control is used to exhibit the information occupied in the structure of NETRESOURCE. [1] Users and groups Members of a group could be enumerated by carrying out a search in the Active Directory Lightweight Directory Services (AD LDS). To limit the type of selected object a filter could be used thereby accomplishing the function by using the set aside techniques. To find the data in the LDAP query syntax, Active Directory Domain Services is instructed by the filter in the query. In order to search in Active Directory Domain Services the below mentioned technologies could be utilized Directory Searcher The system is meant to provide the Directory Searcher class. To allow searching within Active Directory Domain Services with .NET Framework, namespace is provided by the Directory Services. IDirectory Search To query an Active Directory server, as well as other directory services such as NDS, by using LDAP, the IDirectory Search interface is rendered by the ADSI. Data typed in an abundant manner, such as Integer, string of octet, descriptor of security, UTC-Time and Boolean are returned back by the interface of COM such as IDirectorySearch. OLE DB Irrespective of the type or location, data is stored in diverse data sources with uniform access by the applications. These applications are rendered by the set of COM interfaces such as OLE DB. In order to access Active Directory Domain Services, an application to use OLE DB is enabled by the ADSI. OLE DB provider is also offered by the ADSI To collect the results and submit the queries to Active Directory Domain Services the interfaces of IDirectory Search is used by the ADSI OLE DB provider. To search within Active Directory Domain Services any data-access technology based on OLE DB is enabled by the ADSI OLE DB provider. LDAP API The LDAP API comes under the library function of C-style and the domain controllers of windows 2000 serves as a directory that are compliant with the version 3 of LDAP. To carry out a search within Active Directory Domain Services applications can use the LDAP API. Banners and Applications Banner grabbing is found to be the most fundamental technique of enumeration. Observing the output and connecting to remote applications could be defined as banner grabbing and it could also be very informative to the attackers attacking from the remote area. The type and making of product of the running service could be easily identified by them and it is just found to be adequate to determine the vulnerability of research process in motion. A remote communications tool named telnet built into most of the operating systems is the main dependent factor for enumerating the information of banners and application. To grab banners telnet is the only best option. [2] Auditing The generation of a large number of irrelevant events is immensely reduced by the settings of auditing and it is also used in concealing the important things. A detection tool could be constructed by combining with the Windows Event Collector Service. By building up such tool most important events are combined that is suitable for a specific task of intrusion and detection. Enumeration Techniques The techniques for enumeration are given below: -Names of user could be extracted by using the technique of SNMP -Even by using the email IDs of user, their names could be extracted -By using default passwords information could be extracted -Names of the user could also be extracted by using Win2k enumeration NetBIOS Null Sessions The features in the protocol of Server Message Block (SMB) could be utilized by the NULL sessions that are found to be present primarily for the relationships based on trust. By logging on with a NULL user name and password a NULL session could be established with Windows being a host. By using the connections of NULL session, information such as list of users, machines, groups and share could be collected. It also allows you to find the security identifiers of the host and the user. In order to allow domains worthy of trust to enumerate resources, NULL sessions exist in the networking of windows. With this functionality computers present outside the domain could also be used to enumerate and authenticate the users and even the system account could be utilized to authenticate and enumerate the resources. The information gained from NULL sessions is utilized by the attacker. With this information they try to logon to the system by using various tools that attempt many combinations of username and password. If one wants to disable the NetBIOS NULL Sessions, script of Disable NULL sessions could be downloaded and installed. By using the null user, information about your user names, shares, permissions, groups, services, policies, and so on could be found out easily by anyone who has the NetBIOS connection with your computer. [1][2] DumpSec DumpSec is found to be a NetBIOS enumeration tool. With the net use command it is connected to the objective system as a null user. It is then used in enumerating all the users, groups and information of file ownership. Important files and folders could be modified by the user as they are allowed to do so. Even the system wide changes could be carried out while performing on Win NT/2000. Because of this permission user could delete the important files could by accident or intentionally. Even someone might misuse the account to crash the system. Various file permissions and user rights could be checked out by using the DumpSec tool and even the holes in the system security could be identified by the administrator of the security system. For Win NT/2000, DumpSec is used as an enumeration program. The permissions and audit settings for the system file, printers, registry and so on are knocked down by this tool in a more compact and readable format. And even the information about groups, users, rights of the user, policies of system and services are dumped. Many other information related with the policies of account, audit, and trust worthy domains could be got from DumpSec. Security settings of the local or remote system could be knocked down by using the Dumpsec tool. To perform all these functions DumpSec must first log on to the remote server with the privileges of administrator in order to get an access to a remote system. Hacking Tools In order to locate the information about NetBIOS many hacking tools are designed for scanning IP networks. NetBIOS Enumeration Using Netview NetBIOS shares are enumerated by the tool named Hyena. Apart from that it can also exploit the null session vulnerability to make a connection to an objective system thereby changing the path of share or editing the registry. Other NetBIOS enumeration tool is found to be the NetBIOS Auditing Tool is. By using this tool several checks on security are carried out on remote servers that runs NetBIOS file sharing services. List of computers displayed in the specified workgroup, or shared resources available on the specified computer are done by the Net VIEW command. Most of the browsing functions available in the neighborhood of network could be executed by using the NET VIEW command, but workgroup list could not be viewed. A list of shared resources on your computer could be viewed if you use the NET VIEW command along with the name of your own computer. If the NET VIEW command is carried out with a computer name, then the list of available resources on that computer could be easily viewed. The computer name could have the name of SMB (Microsoft) or NCP (NetWare) computer if you use the Microsoft Client for Microsoft Networks and NetWare Networks. If the NET VIEW command is used without any command-line parameters than a list of computers with computer names could be seen on the left side column with remarks on the right side column. List of NetWare (NCP) servers under other servers could be viewed if you use the Microsoft Client for the networks of NetWare, apart from using the Microsoft Client for Microsoft Networks. NBTSTAT Enumeration Tool By using the NBTSTAT tools comparing of various other tools could be carried out easily. NBT Scan A sub network, searching for machines with NetBIOS shared resources and logs is scanned by using NBT Scan. To carry out the scan of IP networks for NetBIOS name information NBT Scan program is executed. NetBIOS status query is send by it to each address in provided range and provides a database in human readable form with all the information received. It lists the computer name of NetBIOS, IP address, user name logged-in and so on for each replied host. GetAcct While opening an anonymous login, information such as the name of the account, type of account, policies of password, status of the account like whether it is disabled or not could be shown by using Get Account tool. Null Session Countermeasure Based on the operating system used, NetBIOS null sessions are a vulnerably found in the Common Internet File System (CIFS) or SMB. If you log in to a system without any username or password then a null session will take place. By unbinding WINS Client TCP/IP from the interface, services of SMB could be completely disabled on every individual hosts. And even the registry to hold back the anonymous user could be edited. PS Tools PS Tools is a collection of enumeration tools and it also provides you with a set of command line utilities using which you can easily manage the systems placed in local and remote area.[2][3] References 1.

The Best personal loans are here for you with No Credit Check and No Waiting Time

The lending and borrowing process has always been there in the society from ages. With bankers and financial institutions coming into existence they were properly streamlined and different types of loans came into practice. These loans can be broadly categorized into two – The secured loans and the unsecured loans. While secured loans require some kind of security against which the loan would be sanctioned the unsecured loans are sanctioned without any security. But they rely highly on the credit scoring of the borrower that acts as the credential for repaying capability of the borrower.

As the risk involved in an unsecured loan is higher the interest rate would obviously be a bit higher when compared to secured loans. But the positive aspect is that even if the interest is higher it is most suitable for all especially for those who have nothing to back upon as security, to get a loan.

Interestingly there has been a change in this aspect too. Today most of the personal loans available are ‘No Credit Check Loans’ making them the Best Personal Loans that one would prefer for.

Today, the economic condition of the country is quite bad and when it comes to the individual level it is really a tough time to fight against all the rate hikes and increased cost of living. Adding to the woe, the main sufferers are those who have already run into many loans in the past and have been unable to pay in time thereby bringing down their credit scores. Despite all these downturns their situation is no better and they still require financial assistance to come out of this mess.

Keeping this in mind many financial institutions have come up with the Best Personal Loans possible that would be of great help to people with bad credit scores. And this is the ‘No Credit Check Loans’. Under this scheme, any person who fulfills certain criteria can avail this loan despite his low or bad credit scoring.

All that it requires for these Best Personal Loans are simple enough to meet. The borrower must be at least 18 years old and a US citizen who is employed for at least three months with a steady and reasonable income and has a valid and active checking account in the US.

When the details of the above criteria are provided in the application for the Best Personal Loans, your application would be processed and the loan amount deposited directly into your bank account. The processing of the application is quite fast and hardly takes 24 hours time within which it gets sanctioned.

These Best Personal Loans come in as a great savior when one confronts a sudden financial crunch and you cannot wait even till the payday. When you are sure that when you receive your pay check you would be able to repay the said loan you can avail the Payday Loan. This is one of the many Best Personal Loans that are short term in nature and once you get your pay check you can repay the loan and be debt free. Apart from this, they also have the option of paying it in part payments and also, if required, there is the option of extending the repayment period or even going for a new loan contract where this remaining debt amount would be rolled over.

There are many financial institutions out there in the market who provide these type of loans. The maximum amount of loan sanctioned varies from institution to institution and so is the interest rate and repayment structure.

Before deciding upon a particular lender, gather the details and facilities provided by various FIs. Ask them various related questions and queries and make everything clear. Analyze them well and then make a prudent decision. This would ensure that you finally land upon the best possible deal.

Apart from the no credit check facility the other advantages of these ‘No Credit Check Loans’ are that they do not require any collateral security and no huge documentary proofs. The waiting period too is less than 24 hours that make it to be the Best Personal Loans available. Life is truly much easier with such personal loan facilities provided by these institutions. It helps us come out of the financial crisis in a timely manner while it itself is getting benefit by way of interest. So it is a win-win situation for both.

Acne Treatment – The causes and the tips

Misconceptions between Acne and Pimple

Most of us thinks that acne and pimple are same. But, it is not. Acne is a disorder or a skin condition
that is caused by sebaceous glands and sometimes by inflammation of hair follicles where pimple is
caused by acne and it looks like a round bump.

What causes Acne?

Acne is caused by

Diet we normally intake everyday
The hormone changes or hormone levels in the body.
Adolescent age
The Environment where we are
Genetic Dispositions
Sebaceous glands
Exposition to Sun
Squeezing and picking the acne spreads the bacteria to other places in our skin and that causes
acne to appear more.

The treatment

Acne treatment should be taken based on a skin condition. People who are having dry skin, should choose different type of treatment and those who are having oily skin, should go for different type.

Acne treatment for Oily Skin

People who are having oily skin,

1 ) Should concentrate on eating habits. Oil items should be avoided and foods that are rich in fiber
and carbohydrates should be taken more. A daily routine of lemon juice or orange juice or amla
is must, since they are rich in vitamin c

2 ) A oatmeal mask can be applied to the face. This acts as a good scrub and take away excess oil
from the skin.

3 ) Mixture of a sandalwood powder with rose water can be applied to the face and can be washed in 20 minutes.

4 ) Egg white and Garlic has a rich antiseptic properties and can be applied on the acne areas.

5 ) Usage of Cypress oil is preferred because, this helps in promoting regeneration of cells and balances oily skin.

6 ) Bentonite mask that is made up of apple cider vinegar can be used. This helps in reducing the pores in your skin

Acne treatment for dry skin

People who are having dry skin,

1 ) Should use foamy skin cleanser every day and night that chemically induces the dryness in the
skin.

2 ) Moisturizing creams preferably gels should be used regularly in order to avoid having excessive skin flaking. The gel you are choosing must be non-comedogenic.

3 ) Acne Medications should be avoided.

4 ) Oils made up of tea tree, sun flower, black current seed can be applied to the face.

Common tips for both the skin types

This is a list of common tips and can be followed by everyone in order to avoid having acne.

1 ) Drink lot of water

2 ) Do not touch the acne affected area

3 ) Reduce stress levels

4 ) Do Exercise regularly to reduce the toxin levels in the body

5 ) Whenever, you wash your face, use a soft cloth and dry the acne affected area gently.

6 ) Wash your face twice a day and do not apply anything on your face while going to bed. Let the pores in our skin breathe.

7 ) Avoid foods that are rich in Iodine.

8 ) Avoid Smoking.

9 ) Consult a dermatologist before doing home remedies.

10 ) Try to wear loose clothes if you have acne in your body.

Acne Treatment and Diet

Does Diet Actually Affect Acne?

In contrary to the beliefs of many people that genetic predisposition was the major factor that affects acne appearance; today studies show that there are a connection between a particular diet and the acne. Foods that are rich in fats are said to increase the insulin level in the body and has been connected to a hormone similar to insulin called as the IGF-1 production.

Is there a Connection between Diets and Acne?

Population studies propose that acne is prevalent in developed populations compared to the rural people where the use of dairy coffee, products, alcohol, oils, cereals, salt, and sugar was at the least amount. Other food that may add to acne including nuts, cakes, chocolate, oily and some fried food.

Acne is an observational learning that assesses two inaccessible non-westernized populations who has a lack of acne: the Ache hunter-gatherers in Paraguay and the Kitavan Islanders in Papua New Guinea. Researchers wonder that the low-calorie content of diet which they have results in a low-glycemic index which might be the cause for the lack of acne.

Is the hormone or the fat contents that affects acne?

You have to know that not all fats affect the skin and not all also are good. There have been studies that link in the consumption of dairy products with acne. However the interesting factor is that skimmed milk and low fat milk that was connected in acne also suggest that fat content is not the cause.

Is there a healthy balance?

Well it is evident that nutrition plays a vital role in the health of a person. It is the same study that connects dairy consumption in the prevalence of acne that some foods can also lessen the condition of acne. Low fat diets, high fiber foods tend to lessen the condition of hormones connected with acne. This means that you can balance the variety of foods that you eat. You can east more vegetables, fruits and fish.

What can you do is acne are already prevalent?

Well, you ca find lots of acne remedies and treatment both natural and over the counter. The acne remedies will allow you to spot treat the condition varying in the cause. Exceptionally oily skin is the result of the hyperactive sebum glands. When too much oil reached the surface of your skin, the bacteria can easily trapped in the pores that will cause pimples, congest ions, and blackheads.

If you have an oily skin, the acne treatment must include a non pore clogging ingredients just like aloe Vera and jojoba. You have to remember that you have to keep your pores clean. Anti bacterial organic extracts and activated charcoal can dissolve excess oil in your skin and prevent pimples and acne without drying your skin. And lastly, always employ an alcohol free astringent which will balance your skin’s PH level.

The product that has an organic black willow bark and physically occurring salicylic acid can help fight active breakouts and discourage the appearance of new pimples in your skin.

Ship buried in 18th century unearthed at WTC site

The 32 foot long ship hull which was buried in 18th century was discovered by the employees who were digging at the site of World Trade Center. The Archaeologists Michael Pappalardo and Molly McDonald were available at the WTC site when the employees exposed the object on Tuesday morning.

The archaeologists said that they observed timbers that the incident has given. They also found a part of the vessel and tried to clear it in two days that were exposed.
The archaeologists work for a company where the documents about the artifacts has to be submitted which were discovered. When asked them for the results, they said they need to do more research on it.

They also said that they need find the ship’s age and so they will request an
endocrinologist to visit the ship and take it to laboratory to make research on it.
They also found an anchor at the site and they were not sure whether it is a part of the ship. The archaeologists were trying to find out the details of the ship from the time it was exposed. Pappalardo said that he was thinking about how it got destroyed.
