Abstract Row-level security has a feature with longstanding development. It can enforce users to reference or modify part of rows according to the configured security policy. So, we can utilize this feature as if virtual private database on other commercial database, however, we designed this feature much carefully to keep both of reliable security and minimum performance trade-off. In addition, we enhanced usability to allow row-level security policy using usual expressions, also plan to integration with label based mandatory access control. This session introduces which was the problematic scenario being called "leaky-view", solutions for them as basis of this feature, row-level security feature being newly supported, and the future plan towards integration with label based mandatory access control. We don't assume audience has deep knowledge on planner. Typical use cases will be helpful for web-application developers who like to ensure reliable separation between users.

with I'm OK and this is my Special unsinkable adjoining and Michael In this talk we called my sister role that the security of trying to look up and find growing access control feature of wall of the 1st year of Boston 9 . 4 Note Finder points
1 thing that I have to operationalize no decision is cut to rise to truck was a 9 . 3 feature of but when have some media although through will you call and I want all the role reversed the whole body of 9 . 3 features but and it was the Victoria postponed to Argentine point to recycle so so it is the epitome of such hh they
almost ready I encourage you I concluded that the measure of its long instead of which motivation and so on seems his but from stores and so Ross along is a measure of the role of the cell and we're right to also with respect just the
rest of the which shoulders data discrete yeah it is they on to show a hollow for all of us could you know walks generally there too often with the foreign shock and also with you know all of us are classified as security level of that these ideas on the spot but he these other will to access the secret so origin and 4 shown here is a a summary of the Secretary-General's the highest 1 is a sequence of next long he's crossfire some role which 1 is much In this context we write to restrict are also to be a return to the user 1 and you don't use the wizard crosspoint credential access the role of expected result is that for all rules z are all built us and frostbite or ratified but and secret coupled multi breakdown of of return to use although the the blue users he was and of classified credentials it was also user can get full roles from this terrible but brilliance that will will get to topple hold their things in his presidential is only to ashes only on across fiber but the classified and secret of invisible of some of the is
right even tho also curious as to all want that was here of the quiet prior to join all examples a user ID these are summarized in these as you have a table is shown by multiple views of the identified by so body in In this case and ID equal hundreds tried to locate and get the result from during all their and during ways that she was not the rise by during products In this guest it's a greedy policy is actually ideally all during all the people all the should ideally all should the old their subjects such issued the query in this area In this and only attack already topples with special lighting equal and an query in bulk up our rate down to a set of slides 0 it was joint tools such as joint 2 was a total of and of boring without secreting already and so what what's the disparate restrictions are all tool oral too high on related couples wrong so use y
and y and and went to world we need to implement those creatures origin which version rats consonant the z is a typical case it's this diagram shows of potential issues there could 2 also regularity and potential and issues occurring with the appropriate to to conditional to restrict restricted are also to be URI wrong thing about all users but also on the will of dual-use I when rule you the users applications and this application intermediate at the request of all member who use of the issues in query to the database which is an opera create way for us to show also are also to vary and you will use of scenario that competition and issues that come forward with where possible euro you have the right to you but and this structure of the 3 structure of all the all the the apparatus shown how responsibility to set up appropriate other operator condition for restrict the rebels that means and we have to make sure the applications above for a all-volunteer ability but it is it is a alright and difficult to achieve since would you tell you the is that many applications in general and it's a number all points to be checked and grow also possibility of biological or ability and that's the a stem from so I like to move the responsibility to set in such a way that across all restriction to want also recalls into into the database in this diagram and applications and machinery issues the same queries but also because you itself off and there appropriated with Ross who restrict restrict the a youth if the task we moved to the rest of the N. wrong that application was that about all we have to a chair in it was Quality of sequential he or she is quite 1 not only 1 it makes them it makes sure of them were part of all the secretary which involves the application of barnacle all volume the majority and I have to enhances the walls of rupture with the integration of acid X 4 assumed applications of what goes on behind all of our troops self 1 of the rule user and according to lose it when someone went somewhere around 2 publications on because all the itself and we in sort of module 0 to to ascertain appropriate prevention according to the use of that that's schools that interview regret was sort was it applications of of previous as switched to wear blue or you know all right now according with the use of once up provisional breweries it's queries and it it's queries spell restricted by our security forces that us the centroids of all working within the or z In the structure of oral to temporize the centroid of the monitor and all the wall of the system's security policy into a long process 1 right means a security policy all but
so it is that our model based on that and need to allow it to need to learn from that of doing so time to time looked up and probably you can consider your is a simple solution right there you with that where right so what example the disk Create statement this creative statement of tried solidifying out you z periphery a direct quote from during the day I'm this is where profit constructive Zeyrek all such as housing prices role was to 100 than the weight on grants so that the reporters who would it all these you poverty so on user can refer as you with referring to the periphery of the right for since Z during a table of the most of it all this you know it's not our tool refers to a public use emissions all recently of possible SQL denied access role but here is a vulnerable all right see so this example of sort of stuff from sulfur going where it really it is a function of a device FIL curious 6 the all-pole fall is the same content some content words what we just we see but here are easier to suspects show articles that will be what was that I'm
defined set every functional was this was this differential privacy the burning small along these functional Horse side ever thing is that this function defined during an will by on freedom to rule so even if we put dysfunctional into where across all of and iterate down through with all of the input but it rises and not this because of causal that all right see it's it's it's raining result so let's start from fulfilling way now if we it's sequence shows junk on storing and there is here and it has a few condition infrequent onto price resident of of once in the area the last thing we have to know all of all is 3 is about it's already at the moment and so the people on the show the price rest rest 200 that all all you would expect it's priced rest sent to convert shall be an invariant already at an origin of cells but Due to use very small cost In Greek shall be origin already and sparse eat rice and noticed it was causal been tried it breaks that record it it breaks contents calls are called to be invisible for
I'm yeah it's an unassessed scenario awake can really invisible content all invisible right Red season this differential you and create a new way all answer it this view shows the result of all the food but if all joint all to a different levels of geographic on the right along we this the value in your own tools to your right and you know who the correct probabilities of very usual carousel on every with joint and and so on up up up that so on this all the way up the right of center it is often in a lot of is all now all you would expect the user can see the red called recalled old low content can all everything in the column then and what's happened when we put them in freak function on this view so let's start from we boast where every what why belong to was here so we can check ex-prime result In Greek is evaluated during the sequential steps on here the quality because primary mission down the use of the quantities in the people sites all this scam from faintest did this filter ondition can reduce the number all roles to be joint it is a it is usually found that out some of the bar at and this condition after joining the wrong perspective people all Homer think but it is not good wrong the Post there is also in the since that in function can be foreigners zip recalled to be following
what's appropriate to the type of In this does the on all you expect is the frequency of course require the out of the way across the in and it restricts the recall to be x also was not x also and only x also recalled should be evaluated by use of conditions but in a query from the yield the the variation all the conditions and so on we need
some future a user given condition from outside that you we called it the emitted by of it
is it already must of future in possible you know what I'm going to so it is already in other 1 now we have to know waste security body across all you initial it ensures that all that to ever it is that when products right see as a result of this query it is the same while roles of of right but it's result was different since well wait and issue that clients said stuff from Salt link where every indeed an integrated hold also recalled that to be a evaluated but the upright of all right after the dual after after the system although according to where across the hall here within beauty of initial set all every pair x also is so recalled to be visible for right seizing
explain cross is trivial the example every quarter lost to lose the quality of the price arrests to 100 but 1 way we when we are that you security but body of a review it just on the use of all that awarded the human condition that also rescuer query from our put it creates that outside all these skills from all of the role it ensures that its instances are a I also to will be passed to rate is always visible or user well but the you can see it has that the bond energy all of my vision for of the all the secretary he always every piece of unfinished form of performance prospect
let's see d'Este example and create you might came with body and also some bone employee will also equal or can't use you as you already know it called on the show and tell it's on bits to index but the security body approved don't push down these people on into the situationists scale fact and we have to to scan all the employees are also even if each house and Muriel over all then it checks at its ChIP-seq peak people on the the all above it is it is is it also said it is it is it will cost them of prevention all the down is not the same as this integer equal oral condition is all we have 3 Congress it doesn't have any outside that so here is not passed through it also people inputs tools user sites following series and
we need to just to break security barrier also we call it the group function it is also this
feature is also integrated all possible security and . 2 if indeed it is out of Africa all of functional world which up at all its credentials when we looked at the rate approved operated in the function definition it's even also cyclic by selection all example dysfunction dysfunction obviously doesn't really anything here is right common full weight as shown in these functions 6 that 0 great through and Z and this function is defined with the rule of a right sees a result also explained a well across a given by user is defined there just would book on this is called the show is the this condition is lost warriors and we must waste that conditional tho well we previously defined South and let's see let's see if the conditional parentheses and explain results the all In all example and it is up here as well as of prompt the user defined function doesn't have a weak grew up at South disk query client indication from our it from the pool of sequence of and the a sequence of and it's not the 2 sequences here on the wall so long as you are conditioned on the use of and will function of corrupted in rats and not that but once we for it and so the use of who we example of these things sort of fall the double 1 z bill bill example and shows the probability that shows very on regular defined you with ID equal 3 on In this example of this example all to world pushed on z given on the shore in an inclusive index and out also if you run conditions and we could be cured condition of integer that time is the mark of the group until all only that are also not all those recall with index index quantified equals C 100 in a large chunk of the truth of recalled by a freedoms recalled by the boss correlative just
as what also have I asked my story you are in charge of all or will comprise a new cases interests oracle they they Scholes meaning this season it explain of course when when I use and doesn't have a politician who are pretty far as it will be all those of you In this case are In this case of view of quantum and the tool animals being joined table the table a on the table it was also a user other condition that Japan already has been only it's all temples it and it is a but it is also point 1 if you don't agree increase at x equals 1 and in joint shoulder and the table of preparing or mission of individual checked so all who is also waltz wine from us that all the security but it clearly shows 1 of will requires a what required through and 2 adjoining walls were all wrong both sides then eat at prices conditional given by users even if it is it is it is Congress so I think that it is the quality of montage all possible through who or and I also like to know that other commercial so that database is the idea right on MSN sickle cell or all of the of if you will of environmental states that the rest this term is it's right
I'm these nouns the background sorry I was on the interval development cycle all also a secure voice and 9 . 2 it has a new future although security body on the street of then and right who what warnings about security but as I told all the glove was born the bottom 9 point or development cycles so the scenes that I've introduced here he's down from unlike from the 2 sub meter subcommittee parties to what's what in 9 point or the whole development cycle to be all the next year tools role
reversal in the future I want to look at the if statement that an overall that called hill of what you know security policy all about what Europe to and it is implemented of up some among all of the other on the table set role of security for command the type common type shows all set in set up data but the initial margins for support all tool expression expression means that expression man named quantization tool restricts the report to be exposed to users all it is it is a regular expression of Wal-Mart to be we used to be that we use are put as well across his square and will example and undetectable might have central route security for all to and any wasn't tool equal to it means that the content of an equal even by all of these expressions can also on some query the visual example shows that the columns and all of my terrible up too too much any all of our results all of us hope it will how to how does
it work 1 way put on these policy or all known before corridor on the use is X on these 2 parts per user ID depending on the part session upholding the tools secretary portion state of the other of all when we when we're requires that have working at these it's funded us if the table he content the sub-queries ways so bright coalfields secretary ports on it will also be shared us use some query with there some query processing 3 D body offered the soul use of human conditions cannot be called into a subgraph so a weighted graph guarantees the from on the of security policies shall be about it but also sent user people ondition invariant so even if we put a freak function here although every function can x also is a red all user can be you use such as the not on what you and installed 1 exception is that there about the it was all the security policy was upright on Temple of database the value that can bypass be calls database so by user can article 1 for all of them so it is nonsense to protect from 1 database that by use of wrong with that target being that scheme also it took but also makes confusable of things where confusable things you we have private security policy also by user and on the west but graph if we implicitly related hot all right also from query result of PG down with Ross a summary report on the west but go so according to to was a wrong with this question we decided to to give the best by users an excerpt strongly politician from from the role of social security future let's vertices that
season explain results and this query Scholes a regrettable it will but you know what it is it's on through some query of things that 1 way to put it right so it is easily to expand it into index down on an integer comparison of 2 is marked as the speak in all follow the query from our question that arises from in it induces into the some this goes from is expounded to index down on the winery and it for you and you will buy you that's woman of passing it on the on things is that right outside 6 the according to rules of security policy we call that it is also applied on an update and 38 In chessel up there at all with theory all weekend out there is so results all origin Paul we can update these of there satisfied by the security forces and example all recall such wiped out all not people can't use them out of the data on 1 false things is there on the house some wrong so tell us some query stone you want and in the results we use right in and out of cells from us us regular tables itself
it is an overview of all of all of structural when possible if you up with it when we tried to look up the data of that was very terrible but also also this well all stands out of Europe terrible on food on the fetch its content on the theory and the the is on all the audition topic then it is important in the fight with the cross by up there or very 1 sense that fits this so convinced that its wasn't quite ready to by in connectivity of holding through the use of people in the form of our right x equal x cross long and soul then modified to modified and new world marginal recalled content stepped up debated and that older couples of pointed by its CT idea which it is not difficult to modify this structure of holding whose role of security that 1 week out of role of a city or share owns that terrible to be out there this future inject our evaluation of all of the 68 forces it already has a horizontal and a variational radio where from and it through the 1st thing we it almost else you have some queries on rapidity of what if I table grow what does cost of this
class was also no we don't check on security policy on all and you walk on the new what was all couples the updated but it but wrong to look on
checks of checks all security policy on when you Basel all couples who have the property that was unfolding in the Secretariat boisterous freaked our user ID to be equal with the common use the false
false-positive are all who want fiery you that identify since you are it's not checked and owns concentrated new well bottom or recall but if these and it
is undesirable behavior so is the set of all sort Boston so the marginal role of circuit we looked at the checks on according to the new world model to be updated
also also under little and increments model that's broader security involves a lot that we will and we like to answer in a a function that returns a visible or invisible according to this theory of course owns this infrastructural role rural security here In addition to the wall of the infrastructural role of about security it needs and security needs future to assign a security you only use and enumerated type that that can add items owns right and since most sacred the arrival of a secreted orbital is represented as a fixed that usually takes the solid-fuel fuel 40 but the if we have to look about in this society you off all the bytes of text so that you will also recall of heat between corn shown this expressed in souls and most of all it's part of the course so I right who would like you to rights enumerated type to compress the disk space consumption of the majority of other future all of evoke as his years during which it is of quite a private all with the despicable and if the user
results of all this I already have also parties to work on it 1st of all what a 9 . 4 the cycle on so we can check their and induce the future jittery was variable mine and then we summarize a brief overview of all these features with the 1 and removed from the remaining time right a
right to expect upset OK any questions from you thank you and I'm not I'm I'm I'm just I'm not I'm you know and we then is a read through functional because a simple use of the variance in that are shown through by user thousands of if you have any and all nationals on to that system he believed that in which Hamilton across the databases by use of all of all of the things that it breaks old assumption here that we actually databases by using is for us and that they don't have they they don't do something about so and so but so I function and has to be checked by right all the support of also in here right so they're called function to be concentrated on being at the time right that the Quran operator all integer and we already marked the sum of all fears for a home responsible was really so there are some all some all on this on the right in this very curious about which the down into security body it is the reason why we can we can use the core of Europe on mission to and demonstrate its aquarium was instructed to index that the answer questions what center for joining and
