Log masking in java

I used a free weather webservice as a sample for this post.

Understanding Java Logging Hell - The Basics - Java Logging Hell & How to stay out of it

I created a GlobalWeather. To log the webservice requests and responses, we need to change the handler resolver to our custom one. We are going to add our SOAPHandler implementation to the chain and that way, our logging handler will work before we send request and after we get response.

During this times, we can easily log necessary information. Firstly, I will show you the logging handler. There are 4 methods we need to implement:. Then our main class stands below. As you can see, we set service handler resolver to our custom one at line If you have question, you can ask me anytime. I am trying to implement a stand alone web service client. I am able to create the SOAP header request with username and password. I have managed to find out the problem at least in my client side.

The server is using this string for some kind of authentication unknown to me. I am facing the same issue when the same code is working fine in a different machine.

First and foremost thank you for this post. I too have implemented the same process to log my inbound and outbound SOAP requests. I wonder if that can be changed. Do you have any clues? I will look for third party libraries in near time.

If I find a way for formatting, I will let you know. Today I found a little bit time and solve your formatting issue.

If you check the end of the post, you can see the solution. Thank you very much!

Hello sir! I have applied your code to my project but it seem no any log print out.

What should I do? Did you set the Handler Resolver to implemented one? I need a little bit clue about how did you implement the code. Hi Thanks for the article.Deploying application into secure environment adds some restrictions on logging and log management. OWASP community gives some useful recommendations.

Event log information should never be visible to end users. Even web administrators should not be able to see such logs since it breaks separation of duty controls.

Ensure that any access control schema that is used to protect access to raw logs and any applications providing capabilities to view or search the logs is not linked with access control schemas for other application user roles.

Neither should any log data be viewable by unauthenticated users. The consequence is that you should not use same authentication mechanism to access application and accessing the log files. Also, in some jurisdictions, storing some sensitive information in log files, such as personal data, might oblige the enterprise to apply the data protection laws that they would apply to their back-end databases to log files too.

And failure to do so, even unknowingly, might carry penalties under the data protection laws that apply. When using [logback][logback] it is possible to conigure regexp replace pattern to wipe certain data from log files being written, e. To mask credit card number PAN you may use the following expression logback.

This expression will replace all numbers with 12 to 19 digits with XXXXso some other data will be masked. Another pattern variation honors only digit card numbers PANs with selective first digit and supports spaces between digit groups:. Masking PANs with Logback is the last resort to ensure the data is masked with a false-positive hits.

It is preferrable to mask the data before it is being written to log in the applciation code. You may read about securing coding practices in [my next post][secure-java-coding-best-practices].

Second option is DBAppender to write logs to the database thus keeping them apart from application instance. Other option is to use SyslogAppender and delegate logging to system syslog service. But is is not secure enougth: in the system will be hacked, the hacker may re-configure syslog not to send any events to remote log server. When using a [Logstash][logstash] server, you may send events via Logstash Logback Encoder.

There are handful of appenders. Also, you may consider using logback-audit which provides logging vis dedicated log server or directly to the database. In case of exceptions on production due to invalid data provided in the request, the exceptions may be printed to logs and cause high IO consumption.

This may lead to server unavailability. Logback offers some kind of protection against log overhead. First is using AsyncAppender to queue log events and spread the load. Set queueSize wisely.

Default value is which is not enougth. These async appenders can delegate to any other underlying logback appender, including standard Logback file appenders. Too low values may cause the the blocking of entire application. Think twice before enabling Async Logging! As far as ensuring that a message has been successfully written before the app continues is concerned, you should not log asynchronously.

Specifying inappropriate log levels in application and appenders may cause excessive load on production server. If you always need some information - use INFO level in the application and use the database to save data like raw requests.

Debugging should be enabled on production only in critical situations. Log files should be rotated at least daily. Reasonable log history depth is 6 months. Some regulations may require to keep log files longer for the purpose of investigations.The various components of the FSLogix create comprehensive logs.

Examination of log files is the first place to look when diagnosing system behavior. At the top of each log file, the system records basic information including versions of the FSLogix agent components. Each operation performed by FSLogix components will create a section that contains all of the relevant log entries for that operation. At the beginning of each day, a new log file is created. The daily log files are kept for seven days by default. Log files older than this period are deleted. The default path for the log files can be changed.

For example, it may be useful to redirect the log files to a network share when using non-persistent machines. For each log entry, an entry of zero indicates success. When looking for problems, scan for non-zero entries. A new install or an install after an uninstall will set the default level of logging. A new install will also clear previous logging settings and return to defaults.

An upgrade install will leave all logging settings as they exist before the ungrade install. All values are of type DWORD and are set to '0' to disable logging for the component, or '1' to enable logging for the component. You may also leave feedback directly on GitHub. Skip to main content. Exit focus mode. Initial state A new install or an install after an uninstall will set the default level of logging.

Local and UNC paths are accepted. When logging to the network, be sure to grant access for the Computer Object to the network share and the folder. This specifies how many to keep. If the value is not set, the default is '7'. Default set by install is 2. When set to '0', the specific settings for each log file are ignored and all log files are disabled. When set to '1' the specific settings for each log file are honored.Below is basic console based configuration for masking where packages used for where loggers need to apply and masking plugin annotation as in below program.

In PatternLayout used key as spi which is map with plugin which will mask log text and print as message.

You can also implement for password and rest depend on your application needs. Below is test program to print some log statements which are converting by Log4j2. Below are some more masking ways for different type of data like XML, JSON and printing objects before loggingsending to page or transferring over network.

Edge provides different ways of hiding or masking sensitive data from Trace and debug sessions. You can prevent sensitive data from appearing in the Trace tool and debug sessions by creating custom variables prefixed with " private. For example, when using the Key Value Map Operations policy to retrieve values from an encrypted key value map, format the variable names as follows to ensure the values don't appear in Trace or debug sessions:.

Hiding sensitive variables is an alternative to using data masking, described next. The difference between hiding and masking is that hidden variables don't appear at all, and masked values are replaced with asterisks in Trace and debug sessions. Variables without the " private. Use masking below if you want to mask these values. Edge lets you define 'mask configurations' to mask specific data in trace and debug sessions.

Masking configurations can be set globally at the organization-level or locally at the API proxy level. A list of variables either pre-defined or custom whose values will be masked. For a list of default variables, see Variables reference. This example shows Basic syntax for authentication. To create a mask configuration, use the POST verb to submit a payload that defines the mask configuration:. This is also true if the XML payload uses a default namespace.

Where loggingCategory is the name of the logging category to use. You can append query options to the URI in the following format,?

Logger found in the Registry, the loggingCategory is no longer used to create logger instance. The registered instance is used instead. Also it is possible to reference particular Logger instance using? For example, a log endpoint typically specifies the logging level using the level option, as follows:.

The default logger logs every exchange regular logging. But Camel also ships with the Throughput logger, which is used whenever the groupSize option is specified. There is also a log directly in the DSL, but it has a different purpose. Its meant for lightweight and human logs. See more details at LogEIP. Whether the producer should be started lazy on the first message. By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started.

Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. Whether the component should use basic property binding Camel 2. Sets a custom ExchangeFormatter to convert the Exchange to a String suitable for logging. If not specified, we default to DefaultExchangeFormatter.

If true, will hide stats when no new messages have been received for a time interval, if false, show stats regardless of message traffic.

Whether the endpoint should use basic property binding Camel 2. Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing if supported.

Quick option for turning all options on. If the exchange has a caught exception, show the exception message no stack trace. A caught exception is stored as a property on the exchange using the key org.

If enabled Camel will on Future objects wait for it to complete to obtain the payload to be logged. Show the stack trace, if an exchange has an exception.Any sensitive info like password, credit card details, account details are not exposed anywhere in the application. Log files are the important component for any application, so preventing these data to be logged in these files are one of the crucial requirement. I am going to cover this topic using Log4j2 and slf4j apis, where we can do our own custom masking for the same.

I will just cover a high level implementation of it. To modify our log messages before actually writing to the log files we will have to extend LogEventPatternConverter class, and override its format method.

Log4j will automatically look for this package to see any custom pattern is there or not. If yes then it will use that. Ours custom format method in MaskLog. In our case:. You are commenting using your WordPress. You are commenting using your Google account.
